Wagner Shanghai again, and the afternoon of October 30, General Motors Chairman and Chief Executive Officer Wagner attending the General Motors and SAIC signed a clean energy car project after the memorandum of understanding on cooperation in Shanghai received some media interviews. You in at the signing ceremony, Wagner, the head of the world’s largest enterprises, and nine one-meter on the big man is particularly prominent in the talks, gives the impression it is a young energetic image, in one hour exchanges, I felt his wisdom and agile, free and easy. Perhaps because China is now the only global vehicle to maintain a high growth market, perhaps because GM Shanghai GM to become the United States, one of the most successful, Wagner is a frequent visitor to China, since GM has been in charge of almost every year, each will brought about by motor vehicles to the Chinese surprised and gospel.

“I have more than two years of China’s exchanges, you gave me a lot of good ideas, the communication still want some suggestions and ideas,” Wagner modest start in the dialogue, “The last minute rush, and tomorrow I will serve as the Chairman to attend the 16th mayor of the Advisory Council, and in the past two years have served as President of the Conference. As we all know, GM and China’s development is closely related to motor vehicles, until June this year, GM Asia-Pacific Regional Headquarters from Singapore to Shanghai and will be the beginning of the operation of the first quarter of next year. The focus of the Group and SAIC for further cooperation, in recent years, GM will come up with three billion U.S. dollars of investment to China for Powertrain, local design and R & D, coupled with the signing of the memorandum that the general confidence in the Chinese automobile and commitments. Although in recent months China’s auto drop short-term, but we are fully prepared, because China’s car of the future is bright. ”

“General Motors has medium and long-term development programs, there is the medium-term hybrid technology, has great development potential, especially suitable for high fuel consumption vehicles, such as buses, so we are pleased to co-operation with SAIC in China to build hybrid bus, “Wagner added,” However, hybrid technology is a leading renewable energy-driven hydrogen fuel cell vehicle bridge, hydrogen fuel cell vehicle to ensure energy security so that private car ownership is generally a common long-term It is also the best solution. ”

To this end, GM is working to develop a new generation of automotive products, and even can be said that the car’s design, construction and the drive to carry out a thorough reform aspects. At present, HydroGen 3 is a representative, it is a fuel cell vehicle, the battery is a chemical device, it will combine hydrogen and oxygen, the chemical energy into electrical energy while producing water, the absence of ordinary combustion engine , does not produce environmental pollution. The development of fuel cells as a global leader in technology, Wagner tells us: In 2010, GM will be developed for the commercialization of fuel cell vehicles running on the target technology, at the same time, GM also strive to become the first sale of 100 10,000 hydrogen fuel cell vehicles and profitable automobile manufacturers. When we have one million fuel cell vehicles, when questioned, Wagner explained that this is a scale effect, according to the world’s 60 million when the number is estimated that, if the scale of 100 million will not be able to affect people’s lives, and The role of environmental protection. Need to break through the current technology, GM has invested hundreds of millions of dollars each year to carry out research and development, when the cost per kilowatt internal combustion engine and now is almost the same time, cost reduction, production expansion, I believe that to be able to achieve this goal.

Hybrid cars and hydrogen fuel costs are high, whether or not to appeal to the Mayor of the consultation meeting, the Shanghai municipal government to attract the attention and support? Wagner said that the Mayor’s Advisory Conference title is too wide, not necessarily you, but in the long term, we must be the concern of local government and energy companies have a hydrogen infrastructure, at present, the U.S. government to power hydrogen fuel cars the cost of subsidies. “To achieve the hydrogen economy,” Wagner added, “we have a series of challenges to be overcome, such as building the necessary infrastructure and so on, these issues require the parties to resolve.”

Commented that the industry, which is common at the right time to make the right decision. GM with its huge resources into the global cooperation of the Chinese automotive market and competition, will speed up the pattern of China’s auto industry restructuring and technological progress, while the future energy development and application of the common.

Zhijiang battery leasing services

Battery lease appears quietly in Huaihua Zhijiang. Small county in the North T-county population, the residents of Mao Yan-hui furniture stores to open within a few days ago the public phone battery leasing additional services. It is rare in the province of such services.

Mao Yan-hui through long-term painstaking research, he developed a large-scale improvements in multi-cell regeneration machine, and in line with the reunification of China Limited, a special high-power battery green rechargeable batteries, developed a combination of used batteries to solve the pollution way to repeated use of the battery can not be used to date, easy to deal with pollution-free destruction.

The industry believes that this is the battery industry, “the historic green revolution”, is expected to solve the waste batteries on the environment pollution.

The concept of leasing the battery the green

(Trackback: http://www.todaybattery.com/today )

Chengdu Fangcao rented a house plot, spent 6,000 yuan before purchased under the charger, the Friends of the battery to start its own leasing business. Out from the University for several years, he hoped that his own boss, so choose the brand-new business, he felt that the initiative has attracted.

The pioneer of the concept of ecological

Only 5 yuan of money to pay rent, one month can be free to shop to replace the batteries fully charged, the university campus in Chengdu quietly stall the emergence of such a business. Friends姚官said he believes the industry can prosper because we believe that the community will become more and more attention to environmental protection, the concept of people’s consumption will change as the guide. Advocate green, reduce pollution, the battery lease is in such a concept emerged.

Some on campus put on billboards, and some only in bookstores, paste a piece of paper stationery, campus of the battery leasing business, and there is no trick to choose the campus because there are too many users of batteries . MP3, CD, reading, the use of college students a lot of small electrical appliances, a large amount of battery, battery of students choose to lease more and more, leasing is the battery industry see this. Chuan, who was on campus for students, told reporters the battery, usually to buy a pair of good MP3 points alkaline batteries at least 4 yuan, the general access to 2 days, the cost is not low, and now the lease money to spend 5 yuan , can be used for one month is a good solution.

Quality at a relatively high concentration of the campus population, the environment as a selling point. Ads on the rental shops, all the environmental protection as an important aspect of marketing. Ordinary battery is a one-time, can only be used to throw away, even if collected, do not know how to deal with, and the rechargeable battery can be used 500 times more than the used batteries is reduced by the amount of 1/500 in can not be used with rechargeable batteries, the factory will be fully recovered, and many rental shops because the owners are like the concept of environmental protection to join a national chain.

Reality is not smooth

According to reporter understanding of colleges and universities in Chengdu battery leasing, the charging equipment purchases from outside the province, and prices ranging from several hundred to several thousand, are used in the national chain operations. “If the campus in a 40% of the people is a good business.” Such a publicity ad Franchise.

If there are 2000 users, I can make money, and had to join the Friends of chains have been considered when this account. Chengdu, Yao said he was the first to do this and add to the cost of foreign visits and spent money almost 20,000. However, in September this year when he received a charger, open for business when on campus at the same time there have been several other rental stores, about 45 brands of chain together to take out. More than a month later, he also only a few dozen users, very difficult.

Competitive campus, he focus on the residential area, and a toy and residential rental shops signed a cooperation agreement, hoping that this would expand the scope of chain to the entire city. Almost one month, and now he has not yet become members of the public users of the change in consumption habits was not easy. After all, this is a business of a few dollars, it is not very much. In shopping malls to spend a few dollars can buy a version of the battery, to allow people to change consumption patterns is not easy, this is bigger impact on the battery leasing business the biggest obstacle.

More people need to understand

Although the operation is going from bad to worse, but that is promising. To ensure that the battery recycling, used batteries to reduce pollution, this is more like a bad business is a public good. Faced with the concern of journalists, rental shop operators believe that the benefits from environmental protection and long-term perspective, development of a multi-user, and its economic benefits will be reflected.

Rent not sell, rent a cell, leaving behind a piece of green. This environment-friendly battery to die-supported leasing industry forerunner. The next thing is how to make it socially acceptable to a rental shop owner says Yang. On campus, leasing the battery industry has been aroused in the emergence of some concern and discussion.

Wu Yue said that environmental protection volunteers, the campus is a battery-leasing industry a good way to conserve resources for practitioners bring a revenue benefit to the students, I believe students will take the society to promote this approach can be. Far point to say, the whole community to reduce the use of the old battery on the environment is always a good thing. Ordinary batteries can restrict the use and production of it? Environmental issues should be supported by society as a whole ah!

Today, the streets, carry small electrical appliances for the audio-visual widely used, the battery usage is also increasing, the battery can become a new lease of consumption? needs Friends of the dream is the idea of such consumption and choice.

60 kilowatts of fuel cell vehicle to complete road test

At the national’863 ‘and the CAS Knowledge Innovation Project of major projects under the auspices of the Dalian Institute of Chemical Physics, Chinese Academy of Sciences to develop the fuel cell engine has made significant progress, the second generation of 60 kilowatts proton exchange membrane fuel cell engine in Tsinghua University completed 150 hours of hybrid joint debugging, loading the engine city bus to complete a total mileage of 3,000 km examination.

60 kilowatts of second-generation proton exchange membrane fuel cell engine used variable improved operations, in February 2004 at the Tsinghua University to complete the installation of an integrated city bus, driving the success of an urban traffic route in live operation, which was recently successfully completed 3,000 km assessment of the cumulative mileage. Total vehicle mileage 3127 kilometers, the maximum speed of 70 km / h, maximum daily mileage 303 kilometers, the test results are to achieve the desired goals, setting a national fuel cell city bus a new record.

At the same time, in accordance with the National’863 ‘electric vehicle significant specific fuel cell city bus of the second phase of the project contract, in July 2004 successfully developed 100-kilowatt fuel cell engine, was on September 1 this year at Tsinghua University adopted by the Ministry of Science and Technology’863 ‘Group of Experts, vehicle units, Tsinghua University and the National’863′ program for electric vehicles to form a special Commissioner of the Department of the test group test, the engine maximum output of 156 kilowatts, 100 kilowatts rated net output, the biggest net output of 120 kilowatts.

Mobile power generator developed by the United States

(Trackbakc: http://www.todaybattery.com/today )

U.S. engineers are for mobile phones and other mobile electronic devices to develop a new type of generator, this generator is based on the principle of jet aircraft developed engine, not only convenient to use and powerful.

For conducting this study is the USA and Georgia Institute of Technology scientist David Arnold and Mark Allen, they have created the first silicon-compatible device, there is a network of interlaced scanning coil etched on a chip, a small magnet side-line in the rotating coil, and by the rotation of the “micro-generators” of the mechanical energy generated into electricity can be used.

The key advantage of micro-generator is enough electricity for every increase in fuel generated electricity a conventional lithium-ion battery for at least 10 times, In addition, the possession of space, but also flatter than the fuel by the cell phone work better. Arnold and Allen co-operation with the U.S. Massachusetts Institute of Technology scientists explained Stuart Jacobson said: “The jet engine is a remarkable efficiency of the equipment, this engine can be used if reduced to the extent of cell phones, mobile phones will be able to provide a strong driving force. “Arnold said:” We are the first from a micro-devices has been enormous energy. “Allen added that the possibility of such a micro-engine to find the way to actual production to clearance important.

So far, two independent teams are studying how in diesel will be stored in the chemical energy into mechanical energy of turbine-driven, this is the first step in the procedure of micro-engines, the two groups, respectively, and in Berkeley by Jacobsen University of California scientists led Carlos Nandi Spero. Two groups have developed a prototype silicon combustion chamber, combustion of diesel in it to very high temperatures and will not break down, they are granted the scale of manufacturing processes to produce a silicon micro-turbine. However, they are components of the existing access to electricity, the silicon components are not part of the memory.

Now, Arnold and Allen demonstrated the first silicon-compatible chips in the current through the rotating turbine access. They rotate as a diameter the size of a penny coin flat metal ring, the metal ring from each other into a 45-degree angle component of the magnet poles. Due to the lack of testing, micro-turbines used by dentists as as substitute for the pneumatic drill. When the magnet spins, its rapid conversion of magnetic field will have a current map of metal, metal chart on the following placed in the magnet layer. Produced a total of 1.1 kilowatts of electricity, enough for a cell phone or Global Positioning System device power, and Arnold said that this was just a research stage.

To get this kind of electricity will be needed per minute to 100,000, which turn faster than the number of automobile engine, the car engine is only 3000 turn per minute. However, the magnet is fragile, and if too fast, the centrifugal force generated by the magnet will pull off, so Arnold and Allen ring magnets used in the titanium layer reinforced wrap an increase of the width of the thickness of it. They also have to calculate the three-scale interaction best lap, the three coils in the rotating magnet below, used to produce current. Arnold and Allen decided to arrange to 100 microns high, as far as possible to have greater resistance to ensure that the current maximum.

Adierfei in Maryland for the Army Research Laboratory provided financial support for this study, the laboratory of Electronics Engineers said magnet motor is “exciting step”, the next step is to turbines, combustion rooms and generator into a memory chip of silicon. Forecast for the U.S. Army, currently rely on battery power laptop computers, night-vision goggles and global positioning systems combat soldiers will be the first person to use micro-engine. Jacobsen explained that: “the army is faced with a huge electricity problem, the soldiers because of battery problems often in trouble.” Weitz added that the military is concerned, diesel powered device is a cost-effective because they do not lack storage tanks. Arnold and Allen will be held in January 2005 of the micro-electro-mechanical systems (MEMS) international conference to present their research results.

SCE announced capacity PSP battery parameters navigation

Since the PSP portable SCE’s latest release, its powerful features have been attracting a lot of gamers, but the navigation capacity PSP battery has been a player’s opinion, even as Nintendo has been criticized the goals, announced yesterday shocked SCE echocardiography PSP prices, to the Nintendo of a repeat vote, but they play Nintendo or PSP once again the shortcomings of large power big speculation article.

SCE official today made public a series of parameters of PSP, which refers to the normal operation of PSP game time is 4 to 6 hours playback time for the film 4 to 5 hours, the use of relative and generally have been able to basically meet the needs of players (in this writer add that, at present, with a smart power technology for high-end notebook computer navigation ability is usually more than 4 hours), after all, such a powerful (movies, games, MP3, wireless Internet access) mobile games, about 6 hours navigation or the battery capacity can be acceptable, this information is to the players to buy a PSP now reassured.

Bell Labs has developed nano-battery life of up to 10 years

mPhase Technologies and Bell Labs recently announced the first joint development of nano-batteries, while the prototype is expected to be 12-15 months into commercial products, the battery of the invention the use of Bell Labs, that is, the droplets in the electrolyte that as “nano-grass (nanograss)” at the top of the microscopic structure to maintain a static state, after the flow of energies, which have led to the current response.

The experiment proved that the so-called liquid “super-Water Repellency” effect to allow precise control and activation nanograss battery. Nano-nano-battery grass with existing battery technology, compared to have the potential to provide up to 10 years of life and a higher storage capacity. Direct potential applications include defense, industrial, health and consumer electronics.

“And the very fast development cycle of fields such as semiconductors, compared to Moore’s Law, battery technology is usually very slow improvement.” Bell Labs vice president of nanotechnology research, said Dave Bishop, “We are confident of nanotechnology, especially nanotechnology grass technology in battery capacity will enable us to achieve an important leap forward. “

The advantages of fuel cells

(trackback: http://www.todaybattery.com/today)

Fuel cell power generation compared with other unique advantages.

And high efficiency. Without fuel cell power generation from geothermal energy to mechanical energy again to the conversion process, there is no link in the middle of the energy loss. At present, thermal power or nuclear power is the highest efficiency of 40 percent, while the fuel cell power generation efficiency is generally 40% ~ 60%. High melting temperature carbonate and solid electrolyte type fuel cells, emissions of heat can also be used for the second generation. The use of waste heat for heating or combined together for power generation, fuel cell utilization efficiency up to 70% ~ 80%.

Flexibility. Fuel cell power generation device is composed of a number of basic units. A basic unit is a two folder electrolyte electrode plate. The basic unit will be assembled hundreds of them would constitute a battery pack, battery pack and then together to form a power station. Can be flexible depending on the needs of different size to the assembly of fuel cell power plant. The basic unit of fuel cell design standards can carry out large-scale pre-production, so the fuel cell power plant construction and low cost, short construction cycle. In addition, as a result of fuel-cell light weight, small size, high specific power, relatively easy to move up, so it is particularly suitable in remote areas or islands to build power stations, or build a distributed power plant.

Fuel diversity. Although the fuel cell hydrogen is mainly the work of the material, but it can be used for fuel gas, methanol, liquefied petroleum gas and other hydrocarbons. According to the actual situation, in line with local conditions to use a different fuel, or combination of different fuel use, can reach local materials, to save resources.

Pollution-free. The main product of fuel cells is water, essentially non-emission of harmful gases, it is a very clean source of energy. It is reported that a number of fuel cell emissions of harmful gases in the United States national standards for environmental protection by two orders of magnitude lower. In addition, the fuel cell is a stationary power generation, has no mechanical transmission device, only in the control system and other auxiliary devices have moving parts, thus it is the work of a small vibration, low noise.

Due to high cost of fuel cell, generating cost-effective as other methods do not, we can not get the promotion. Therefore, only the cost of significantly reduced and further enhance the service life, fuel cells will enhance their competitiveness. According to the U.S. departments of statistics, when the construction cost of 3 U.S. dollars per watt hours (1994 has reached), the fuel cell will be able to enter the market; when reduced to about 2 U.S. dollars, can be in remote areas as an independent power generating system; When reduced to about one U.S. dollars, the market will expand rapidly. 1 U.S. dollars to achieve this goal, it is necessary to the life of fuel cells will be increased to 40,000 hours.

The development of fuel cells is now very fast speed. In accordance with national plans, by 2000, Japan’s fuel cell power output will be close to 2200 megawatts, the United States will reach 500 megawatts in 2000, Europe will reach 500 ~ 900 MW. By 2010, the world’s total installed capacity of fuel cells will reach 60,000 MW. As a new type of fuel cell energy, is still relatively high cost, long life is not enough, power is still relatively small. However, with the depth of the research work, these problems will be solved. Many scientists believe that the era of knowledge economy in the 21st century, fuel cells will account for in the field of energy in a pivotal position, therefore, have the fourth-generation power technologies, research and development of fuel cells with the significance of the next century.

Dianchi Lake every year 100,000 tons of refuse what way
       Dianchi Lake salvage garbage placed where it? Dianchi Lake every day along the flow of garbage to deal with the future, what will? This reporter visited the HKMA Kunming Yunnan, Kunming Environmental Protection Bureau, Kunming sanitation experts monitoring center after that, a massive clean-up campaign refuse Dianchi Lake basin has been fully launched in the next few days, but the inflow of garbage along the Dianchi Lake how to deal with, it is worth exploring one of the new problems.

Refuse disposal sites will be built lake

Kunming, Yunnan Province, according to the HKMA person in charge, the current agricultural non-point source pollution of Dianchi Lake pollution accounts for 40 percent, and 15 lake township agricultural population of about 700,000 people, an annual output of 100,000 tons solid waste per day about 280 tons. Collected as a result of the lack of lake township removal treatment systems, the main river into the lake and piles of refuse, garbage dumping in rural areas has become the main channel, garbage and sewage directly or indirectly discharged into Dianchi Lake.

To strengthen the management of garbage lake, early this month, the Government of Kunming Dianchi Lake basin has seven districts and counties, as well as municipal government departments to sign “comprehensive management of the target Dianchi responsibility”, 7 District Government and the township (street offices) signed responsibility and the responsibility to establish the risk of mortgage system objectives. 19, Chenggong County, first of all towns and districts have made the preparation of the 60 Board responsible to pay 120,000 gold Dianchi management responsibility to set an example, caused great shock in the county. Lake of the four districts and counties clear 15 township counties (districts) long and township (town) responsible for long as the first in 15 villages and towns to manage the establishment of Dianchi Lake, Lake area is responsible for the maintenance of cleaning the river, rural solid waste the work of removal and disposal of objects. Can not be completed on the responsibility of evaluation indicators, and will not be paid bonuses year-end appraisal, the risk of mortgage payment will also be turned over to the financial.

Followed by the district government, will be 15 in the lake township (street offices) to build agricultural solid waste disposal site 5, each village to build a refuse collection point 1-3 months to build about 700, with 32 removal trucks. These efforts will be completed this year, 1 / 3, complete next year.

Kunming landfill operation overload

Kunming Kunming sanitation and Environmental Protection Monitoring Center of the persons concerned that the current waste disposal area in Kunming City, particularly in the technology and cost, there are some insurmountable difficulties.

It is understood that the landfill, incineration power generation, high-temperature composting is now usually three kinds of waste, but all have their pros and cons of each approach. Landfill garbage is more of the principal means of its shortcomings is an area landfill, and the use of a short time (generally 10 years), high cost, especially in the treatment of landfill leachate has become a from all walks of life he could do nothing but pay close attention to the problem; and waste incineration power generation, it is characterized by a significant volume reduction through incineration to reduce the volume of garbage to make half or more, but the drawback is that the recoverable resources burned, releasing toxic gas, such as dioxins, mercury batteries, such as steam, and produce toxic and hazardous slag and dust; and high-temperature composting of organic need people to separate garbage and other refuse, and some analysts pointed out that it is actually relatively low efficiency, by sale and use of constraints inconvenience.

Monitoring Center, according to a sanitation engineer, the Kunming area currently two things landfill construction scale a total of more than 500, with a total investment of nearly 200 million, was designed daily capacity of 1500 tons, while the actual is overloaded, two each day, “eat,” 2300 tons solid waste, both in May 2001 into the use of the landfill site, originally expected useful life of 6 years to 3 years now time, has removed most of the space.

Dianchi who refuse disposal “bill”

For many years engaged in a senior engineer of environmental engineering calculations to press accounts, in theory, to deal with a ton of garbage to take up to 30 plurality, but far from fees and funding can not meet this requirement.

Landfill in the eastern suburbs as an example, 1300 tons of refuse daily, one-year deal with the cost of nearly 1,500 million, together with the financial allocations and charges may only reach over 200 million, making the landfill Kunming “stretched.” It is reported that the current waste disposal charges in Kunming still uses the old standard, government organizations and institutions to collect 60 per tonne, 20 Enterprise, residents 5 yuan per day, but the actual collection rate is very low, and the gap are in need of financial subsidies .

The Engineering pointed out that generally, to build a large landfill plant will take 1-2 billion, to build a large-scale take more than 20 million, and then told reporters he has a case in point: In May last year, hubbub of the units to be 3 to the joint venture was to invest 40 million U.S. dollars, to establish the first waste incineration power plant, but because of various reasons the project more than 1 year did not seem to have happened since. According to the senior engineers estimated that out of proportion to the input and the actual recovery may be one of the reasons why the project move forward.

Caohai Dianchi Lake Basin to watch women’s collections a year to 10 tons of garbage, the senior engineers are very worried about: “management of pollution in Dianchi Lake were his own, everyone must ask yourself what to do?”

Battery factory explosion

(Trackback: http://www.todaybattery.com/today )

Guardian possession Shuangliu County Road 30, Chengdu Jianzhong Lithium battery factory explosion and fire emergencies. After the incident, Shuangliu county public security, fire protection, security and other departments concerned to investigate timely intervention; firefighters overcome difficulties and in two hours after the yield, however, went for an interview with reporters, the plant has tried every means to obstruct some people. Flames Edward the night sky: a major event in a battery factory!

Living in the vicinity of the battery factory residents said yesterday at 3 pm, they were a “bang bang bang” sound awakened from their sleep. “That sound like the same place salute ring, we get a look, it was found over the flight battery factory flames around the air of a very pungent smell!” Said the residents, followed by a number of staff they will see panic ran out the door to the factory. Subsequently, a number of 110 patrol cars and fire engines with flashing lights swept over the region, a large number of rescue workers into the plant. They realized: a major event in a battery factory.

The door to get: a group of people to obstruct reporters

11 o’clock yesterday morning, Chengdu Jianzhong Lithium battery factory closed the door, the factory staff to strictly control access. Take the initiative to produce a document’s proposed request for an interview, but the guard said, “without incident”; repeatedly asked at the press, the guard, also known as “leadership was at a meeting such as you do on the outside.” 11:40, the reporter tried to find the factory gate to enter the plant an interview with the leadership of representations. Unexpectedly, out aggressive from the factory buildings of 8 men and 2 women, led by men in white T shirt, he roared, “where reporters out!” Lay siege to the side of people’s command. Wearing a blue T shirt a high kick to attack a man’s fists, others forcibly introduced to the factory gate reporters.

Continuous explosions ring: Fire fighting hard

Reporter at the scene only to participate in the rescue from the Shuangliu County Fire Department Battalion captain Liu Hong understand some situations. It is reported that the fire brigade yesterday 3:41 received a report, sent out a total of two fire engines and 17 firefighters, arrived 14 minutes later the scene of the fire battery factory. “In a nearly-square-meter workshop lithium batteries, the smoky, sparks scattered, Fang-ming salute similar explosion of the battery lasted nearly 20 minutes!” He said, there are thousands of workshops about 5 cm in diameter , about 30 cm of lithium batteries, lithium batteries kept these explosions, fire in the fire before the explosion of water and a lithium battery explosion after another, the workshop doors and windows are damaged. Liu explained that the captain, as the fire brigade did not dry powder fire extinguishing device or sand, but to persist in using water cannons to control the fire, finally after 2 hours yield.

Security Council: ordered to cease production of the factory under investigation

Subsequently, the reporter learned from the Shuangliu County Board was informed that security, Chengdu Jianzhong Lithium battery factory to the council submitted a “fire investigation report.” The factory in the report that the accident occurred yesterday 3:30; After preliminary analysis, the cause of the fire qualified for lithium-ion battery plant products due to air humidity lead to short-circuit, caused spontaneous combustion and explosion; the accident caused no casualties, but ” plants can not shirk the responsibility of leadership and management. ”

It is reported that security had been ordered to temporarily stop production of the plant. Armed Police Battalion Shuangliu County Fire Authority and other relevant departments and security are the specific reasons for the accident and damage to property for further investigation.

China has photovoltaic cells, power generation capacity of about 50,000 kilowatts

China’s solar power production and application of photovoltaic power generation is, at present, China has installed photovoltaic cells of about 50,000 kilowatts.

National Development and Reform Commission said that the installation of 50,000 kilowatts of PV cells in remote areas for the residents of the main power supply, which is 17,000 kilowatts over the past two years the implementation of the “power to the villages,” works installed.

Thunder and lightning like the whole house full of electric storage battery

Yesterday morning, living in the East Village I think Mr. Wu to our people on the telephone hotline, 5589999, and said: “The wall at home for almost no reason to bring the voltage to 220 volts, and even has a balcony with flowers power. “tells the strange phenomenon.

Grandpa Wu Mr. Wu and neighbors live on the fourth floor, where the buildings are on the 50’s century-old house east balcony, iron railings around the outside. Around 7:30 pm the day before yesterday, Mr. Wu’s wife to the balcony closed clothes, hand railings when, suddenly felt, suddenly bounce, and there is a feeling of electric shock. Mr. Wu T a measured use of electricity, has found that iron balcony railings and the wall are charged. Terrified family, we did not dare go out. Wu lady next door has its own balcony found the same situation. They had no choice but to seek help from 110. Electric Power Bureau immediately dispatched three staff members. They use more precise instruments to measure a room near the balcony. Did not paint the railings on the bare iron to reach the voltage to 220 volts, there are places where paint is more than 100 volts. Terrace also put flowers on the voltage of 220 volts. Mr. Wu said, but fortunately his wife have run into a place of paint. Staff to turn off two of the gates, but still charged the balcony and the wall. Upstairs downstairs to find that they may break the cables, a tired, sweating profusely, still. 4th Floor, thought the roof to see what happens, just did not expect the roof up when the floor above, and then be electrocuted. 11 o’clock that night, and staff with wire gateway appliance to Mr. Wu’s Zero Line out about the iron railing. If it is the cable which broke railings, zero line of touch, it’s likely due to short-circuit power and the power outage. However, when the zero line of the railings when suddenly “snapped” and exploded, sparks great touch. After measuring and found that all the balconies are not charged a thing. Grandpa Wu said that more than 16 o’clock the day before yesterday she grazed along the balcony and did not find the live. Rain this afternoon, playing a number of mine is very loud. After it stops raining the balcony, she wanted to wipe the rain, it was the balcony on the electric iron, then run into the door was a bit electric. Even on the cardboard boxes on a pair of shoes is also charged.

Electric Power Siming Branch staff repair classes that this relationship may be associated with thunder. There is no lightning protection facilities for the old house, so the whole house like lightning, like the battery is full of electricity, coupled with the relationship between rainfall, making the wall, flowers and shoes are put on the power. And there is a discharge process, in the absolute power until the house everywhere live, close to the roof of the higher voltage. He reminded the public that if the thunder was found after the iron walls or live at home, please timely help to the electrical sector.

Recycling used batteries stop

(Trackback: http://www.todaybattery.com/blog)

“Please put batteries into the trash and stop into the battery recycling box.” Chongqing Municipal Solid Waste Treatment Center yesterday to tell the public: we have stopped recycling batteries.

It is reported that in September last year, the Chongqing Municipal Solid Waste Center for the first time in the city’s recycling network to establish batteries, dry batteries more than 100 recycling bins located in the main city streets, and now these bins has been basically shut down.

The relevant person in charge, “since September last year, the city has recovered about 20 tons of dry-cell batteries, far less than we originally estimated. If the original plan to crush decomposition batteries, carbon rods and copper extraction apparatus, the high cost of , big loss. So these batteries are hazardous wastes are dumped at the Tongliang interchange in the city to wait for hazardous waste landfill after the completion of treatment. the beginning of this year the country also issued a document request, do not promote the recovery of low-mercury batteries, so we stopped recycling . ”

However, there are still members of the public dry-cell batteries, one after another to the Solid Waste Center. Position of the person in charge said that “many people have to treat dry-cell batteries have the environmental awareness of the simple, if they sent, we will not refuse to still be recovered.” “But science has confirmed that the mercury content of batteries which are fewer and fewer of its spread in the garbage heap of discarded and will not cause great damage to the environment. If the dry-cell batteries together buried in the land below, but the existence of environmental problems. ”

Shanghai is no longer the majority of one-time battery to encourage the recovery of

Since the mercury-free batteries can be expanded, the country has been not to encourage the collection of one-time focus on mercury-free batteries, the public collection of waste batteries while environmental protection is the delivery of behavior, still there are some errors. The reporter learned from Shanghai Waste Management Department that will cause pollution of the cell phone battery has become the focus of recovery.

Municipal waste management Department deputy chief, said from Shanghai in May 1998 started work, now has 6,000 collection points. Accumulated to the present, the total recovery of more than 302 tons had reached only 75.54 tons alone in 2003.

It is understood that the market is now more than a one-time low mercury batteries, mercury-based Environmental Protection Agency issued the “Waste Battery pollution control technology policy” that, in the current lack of effective re-use under the conditions of technology, not to encourage focus on the collection of countries have reached a low mercury or mercury-free disposable battery waste requirements. Focus on the current recycling nickel cadmium, nickel hydrogen, lithium ion rechargeable batteries and silver oxide batteries, such as one-off button.

Battery recycling no value

Is located in Anting harmful garbage sorting station director of the Tang and Sheng said a tonne of batteries to deal with the cost of 2250 yuan, but such a deal with landfill curing only, no recycling value, and more batteries into sorting plant will only increase the processing cost.

With regard to the recovery of public misunderstanding,Qi said that although the majority of the value of the battery has not recovered, we will increase the processing cost, but as long as there is battery sent, they are still responsible for recycling, storage. Because of the popularity of the concept of environmental protection itself must change with the times and the corresponding changes. The city to pay attention to environmental protection also includes a white garbage disposal, recycling paper, etc., the most critical in the recovery of batteries concept formed the basis of environmental protection, continue to protect the public’s environmental enthusiasm to encourage the public to the environmental protection acts.

Mobile phone battery pollutants into idle

Worthy of attention is the mobile phone battery has become the focus of recovery. Once-for-mobile phone, the old battery is left idle or discarded with the garbage. And mobile phone batteries, may contain much more gold, mercury, lead, cadmium and other heavy metals, if not addressed on the discarded directly in soil and water pollution, and pollutants enter the body if the food will be a significant health hazard.

It is understood that in 2003 China’s mobile phone users over 300 million. Shanghai Communication Industry Association of the manufacturing sector is Jiang Yong, deputy director of introduction, in 2003 Shanghai’s mobile phone output was 19,675,500, 18,925,900 sales. To a cell phone with two batteries, the only formal Shanghai last year, mobile phone manufacturers has increased by 37,851,800 battery.

Investigation that, in some second-hand mobile phone market, all kinds of brand mobile phone battery models usually offer only 25 million, but these batteries are in use for more than half a year later it is difficult to maintain the normal use, the pollutants become idle.

The original battery in the main ingredient is mercury pollution that the mercury. Mercury will lead to nephrotic syndrome, diseases such as neurasthenia, mercury will exist in the food chain in the long-term, continuous pollution. In China, from 2001 to the phased implementation of the battery limit of mercury content. First of all, low-mercury, mercury-free ultimate goal. Mercury-free battery of the meaning of the mercury content in batteries is less than 0.001% by weight. 2005 ban on mercury content in the domestic product is larger than this standard alkaline manganese batteries; to the 2006 ban on domestic distribution is larger than this standard mercury in alkaline manganese dioxide batteries.
