With the increase in consumption, pollution caused by used batteries against gradually been neglected. China Battery Industry Association, according to statistics: in 2000 China’s production of 18.22 billion cells, of which 17.5 billion a cell, secondary battery 720 million and exports 13 billion, three billion of imports, the annual consumption of 75 100000000. Beijing in 1999 a variety of battery consumption of the total weight of about 6,000 tons.

Used batteries of heavy metals in mercury, cadmium, etc. do not handle, this will result in soil, water pollution, directly affecting public health and the living environment. Beijing Tung Wah Group of Xin Xin waste battery recycling centers in cooperation with the Beijing University of Science and Technology, the use of different biomass gasification temperature decrease with the lowering of the pressure method, the realization of various substances, respectively, at a relatively low temperature gasification technology and thus the separation of waste batteries treatment and reuse. It is reported that the production process does not produce waste water and atmospheric pollution, the whole process in a vacuum sealed system complete, there is no radioactive contamination. Process entirely up to the national “air pollutant emission standards” requirement, no waste residue, waste water generated.

Replace gasoline - Honda fuel cell vehicle display

The emergence of gasoline engine, and lead humanity a big step forward, but when the gasoline engine has been serving for over a hundred years, the energy crisis, greenhouse, ozone and the environment and a range of issues before us. Many long-term vision of the car manufacturer is aware of these problems, invest huge sums of money at, and actively develop new energy power, in the Guangzhou auto show, Honda will show its cutting-edge fuel-cell vehicle - FCX.

Fuel cell vehicles are not the basic principles of the complex, which is based on hydrogen energy, the use of electrolysis of water to the principle of antagonistic by combining hydrogen and oxygen react to generate electricity, drive vehicles. However, if the application of this principle in practice, you will find a lot of trouble.

The first trouble occurred for the hydrogen and oxygen from a key part of response - the response chip integrated fuel cell body. Body-chip integrated response must be small, efficient production can be used in real cars. FCX’s overall energy efficiency of up to 45%, while the ordinary gasoline engine is only 18 percent, but road capacity in a row FCX is still unable to achieve the level of gasoline. And as a result of reaction product of hydrogen is water, so the fuel cell on the environment require a higher temperature, how to solve the low temperature start, traveling at high temperatures, but also the future, Honda R & D of the main directions. However, the latest of Honda’s fuel cell research has been able to 95 ° C ~ -20 ° C under normal working temperature.

Fuel cell applications will also bring in some other trouble, such as when to start and accelerate, combining hydrogen and oxygen to generate electricity and can not immediately meet the requirements of vehicles; and braking, the reaction can not generate the power to suspend immediately, how should Energy recovery at this time then? FCX uses a large capacitor to solve the problem machine. Start and accelerate, the electric energy by the capacitor and the supply of fuel cell at the same time; and uniform motion, direct-drive motor fuel cells; slowdown, the capacitance at the time of aircraft deceleration energy recovery in order to achieve smooth deceleration, and improve energy efficiency. As the capacitor charging and discharging machines when not accompanied by chemical reaction, so a very low resistance, high power output.

FCX hydrogen storage is how to solve another problem. Honda for the FCX is equipped with two large capacity high-pressure tank to store hydrogen, high-pressure tank of the total volume of 156.6 L, although ordinary cars near the fuel tank 3 times, but they continued FCX hydrogen can only travel 355 km.

FCX last encounter trouble is how to integrate these special rational arrangement of the components in the car? In order to make fuel cell vehicles have the characteristics of compact cars, Honda used the unique layout of the whole, has developed a proprietary platform. Consider the characteristics of hydrogen will be a variety of elements of the power system in a reasonable layout of the front bodywork, the rear seat bottom and back. In ensuring the full range of collision safety performance in order to compact size, can be achieved easily accommodate four adults traveling in space.

Honda After solving these problems, FCX has become the first to achieve the commercialization of fuel cell cars. The advantages of fuel cell vehicles is not only to solve the energy problem is to achieve zero emissions, the most direct driving experience that the FCX start, when to speed up the smooth, fast and quiet. As a result of motor-driven, so the gasoline engine roar and jitter in the fuel-cell cars have been not occur. In addition, the start-up and speed up when the machine capacitor power supply of the fuel cell mode to allow FCX to reach a larger power, the acceleration is better than ordinary gasoline engine with compact cars.

However, mass production of the FCX is not just around the corner, this car’s power core - the price of hydrogen fuel cell is an ordinary gasoline engine of 100 times, FCX continuous driving distance as well as the construction of hydrogen supply network can not be compared with the gasoline engine. In addition, the low-temperature fuel cell vehicle to start, quality and size also can not call it perfect. But the chairman of Honda Canada and the United States Yang researchers thought that by 2020, fuel cell and hybrid vehicle market share can reach 5 to 10%, while the long term, fuel cell and hybrid vehicle should be a driving force for technological development necessarily the direction of the mainstream gasoline engine was replaced just a question of time.

China in many respects, not the lack of examples of development by leaps and bounds, in the face of others, with the status quo the automobile industry, I do not know our own staff of Automotive Technology and Research would like to how.

Super charger

Lithium batteries using a dedicated digital camera, the camera will be packaged in a charger. Most people buy when the camera is to buy a battery again, few people would like to buy as mobile phone time to a double-double-charge option. So the market with this type of digital camera battery charger is also rare. A friend of mine today on asked me in the market looking for a Canon S45 camera charger, which really told me a little walking digital camera too but did not really pay attention to these parts all over, especially the charger is is not seen a few.

Fortunately, often in the market around, and some more familiar to the business, so to find a good dealer relations, describes the malicious, the small boy no problem, run the out, time is not long on the back of a charger. Part of the Chargers over the Chinese characters do not have a foreign language, but from the packaging can be seen from manufacturers in the South, the charger can only charge the battery for Canon S45, but also to many types of camera batteries.

Random Flashboard Adapter with three batteries, camera batteries in accordance with different models to select the appropriate board, into the charger base, connected the power supply can be recharged. Charge not only at home, there are packages in a car cigarette lighter plug, so the charger can also be used in the car. It is convenient.

In fact, the technical content of the charger is not very high, but if the Chargers lost after the original, can not charge the camera can not use, so we must buy, so prices of these chargers are not cheap, in fact, get business the price of goods is not very high in all parts of the digital camera, the charger is the highest profits.

The number of charger for rechargeable batteries digital camera, model listed in the above chart, click to enlarge. As for the charger and brand manufacturers, dealers said that she does not even understand, but the distribution that has been sold this battery charger for some time, no customers because of quality problems have been back. At present, the price of this charger is a 280 respectively.

Both organic material solar cells cheaper and convenient

Department of Electrical Engineering, Princeton University researchers has combined the latest research results, the invention can be manufactured more cost-effective solar cells (PV) technology.

Although this new power supply efficiency of solar cells is not the solar cell than the traditional high, but its cost is very low and were able to make more use of. The new solar cells made from organic materials with ultra-thin, flexible, can be affixed to cover a large area in the first-class features, the organic matter in the way printing paste or spray plastic chip in the review can be made of a large solar panels , use the volume as long as the solar panels on the roof of spread can be. In addition, the battery can also be made of different colors, making them attractive materials; or be made transparent, so that can be directly attached to the window.

The researchers now plan to combine the new materials and technology, photoelectric conversion efficiency to at least more than 5% so that the technology has commercial appeal. With the further commercialization of research and development, organic material of the photoelectric conversion efficiency of solar energy is expected to reach 5% ~ 10%.

Hot Electric Bicycle

Electric bicycle sales, battery recycling issue is the development of the bottleneck

Referred to as “small donkey” fuel scooters because the urban environment pollution will be banned tomorrow the road in the urban area. The industry predicted that the electric scooters will become the new darling of the public.

Fuel will be the history of scooters

The rise of fuel scooters in 1995, relying on a separate lubrication system, single-cylinder two-stroke engine, belonging to the non-motor vehicles, but in fact the speed to fast track non-motorized bicycles and pedestrians pose a security threat. Other fuel combustion scooters inadequate exhaust emissions in high concentrations of carbon monoxide and hydrocarbons, have done great harm to people’s health.

In response, the city government in 1997 made a fuel stop on the licensing decision scooters. In the past two years, as awareness of environmental protection among the people, the elimination of fuel rising voices of scooters, the city people’s congress deputies and CPPCC members the city several times to move the proposal. Last year, the provincial Economic and Trade Commission, Public Security jointly issued a document, etc., clearly stipulates that “fuel the use of scooters for the 5-year period shall not be delayed.” Accordingly, not long ago, the city government decided to December 25, 2003 to more than five years since the duration of the license the use of fuel scooters to implement end-of-life, since January 1, 2004, the highway in the urban areas - Century Boulevard - Chang Hung tunnel - Ring Road - Airport Road to form the closed loop (including the road) within the scope of, the prohibition of road traffic fuel scooters. It is reported that the city fuel scooters are involved in 58,000, of which there are 17,000 urban areas.

Electric bicycle and on homeopathy

Electric vehicle is a power-driven bicycle. According to the city of Valley Electric Vehicle Association president Decai introduced in 2002, sales of electric bikes for the whole country 1.6 million in 2003 soared to 3,000,000. Will be implemented in 2004 the “National Road Safety Law,” to determine the electric bike’s status as a non-motor vehicles. It is understood that in 2003 total sales of electric bikes in our city of about 45,000, but almost the size of the cities of Ningbo, Suzhou City, sales reached 90,000.

Electric bicycle and bike compared to the relative labor-saving, comfortable; compared with the motorcycle, the relative energy efficiency, safety; scooters and fuel compared to a relatively environmentally friendly, cheap. Growth in sales year after year prove that the market has some preference for electric bikes.

Ningbo, a number of manufacturers and sellers to seize the favorable opportunities came one after another. Ningbo large-scale access to Carrefour, Hymall more than 40 supermarkets, in 2003 electric vehicle production and sales of 40,000, based on in 2004 to 100,000 red slash. Xinjiang Xiamen city electric bicycle every day leading up to 50, sales of nearly 100,000 yuan. It is estimated that in 2004 the sales of electric bicycles throughout the city will reach about 60,000.

Battery recycling issues to be resolved

Electric bicycle also has “weaknesses”, that is, it uses no batteries, such as recycling, use, environmental pollution can be. It is understood that, at present, the use of electric bicycle aluminum multi-acid batteries and lithium batteries, which in the production process and use of the old battery acid and lead, chromium and other heavy metals, hazardous to humans. At present, the electric car not to discard old batteries relatively common phenomenon, the lower the recovery rate.

Fortunately, there are enterprises begin to take action. Electric car battery production in our province large “super-wai” battery company executives said that next year the company’s electric vehicles will recycle old batteries, make a commitment to the consumer: in 2004 to carry out 10 games in the country “green action” special events, publicity electric vehicle battery recycling old ideas.

Pollution problems

Pollution problems, the city set up a recycling of used batteries of electric vehicles

Reported December 30 in recent years, electric car sales surge at the same time, an alarming number of used batteries, which contain toxic metals lead, the survival of our environment.

It is understood that so far, only the urban areas, the electric bicycle has a number of factories and sales outlets are everywhere. City vehicles to the Department of Building managers should bo told reporters that the BCCI in 2002 on sales of nearly 10,000 electric vehicles, while sales volume in 2003 has far exceeded this figure. I understand that the market is currently used in electric bicycle battery is about 70% of lead-acid batteries, 30% of nickel cadmium batteries, the life about a year. This produces every year a large number of used batteries will be a serious risk of pollution.

How will people’s lives to bring these problems to find the end-result of the used batteries? A few days ago, Electric Co., Ltd. Ningbo city BCCHK building and cooperation, the establishment of a joint in the urban electric vehicle batteries the recycle bin (place in the eight-character bridge), is responsible for processing by the manufacturers.

Fake mobile phone batteries

Crack down on fake and shoddy cell phone batteries, Nokia will take stringent measures

Reuters reported on November 16, the world’s largest mobile phone maker Nokia announced Thursday, had been taken, including cooperation with the police raid, including measures to combat counterfeit mobile phone batteries. Nokia recently the company’s image on their mobile phone batteries due to reports of the fire hit.

Nokia reiterated that the original battery did not find the fire incident occurred, and directed against a third party battery manufacturers products or counterfeit goods, Nokia will begin next year to crack down on unauthorized cell phone market activities. However, they also recognize the illegal counterfeit products are often difficult to distinguish.

The sudden appearance of a large number of recently reported to the Netherlands from countries such as Vietnam, Nokia mobile phone batteries overheating occurred and caused the fire or explosion. Nokia said in a statement, “In each case, the problem proved Neither the original battery batteries, their manufacture do not meet industry safety standards.”

A Nokia spokesman said the company did not authorize any matching battery manufacturers to produce its own brand of battery used in Nokia phones, the company only to encourage the use of Nokia brand batteries.

Nokia also said that companies have to take the initiative in the Netherlands, the United Kingdom and other European countries to cooperate with the police conduct surprise raids and seized tens of thousands of counterfeit products.

Nano Battery

Jinling energy experts “say the sword”, “nano-battery” came in Nanjing

Yesterday, Japan’s national director of the Institute of Materials research fellow, senior visiting professor at Nanjing University Dr. Ye Jinhua made in Nanjing “photocatalytic material in the energy conversion and environmental purification applications and the latest research developments in Japan,” speech. Dr. Ye was raised in the direct use of solar energy to solve the energy depletion and environmental pollution issues such as the Earth’s new energy point of view.
