Battery Tips

Auto saving enhancement, to new subsidies can form good car. New energy vehicle that is the core of the battery, and battery material is an indispensable part of the battery. It is reported, lithium battery level is the cost of materials in the lithium battery cost accounting for about 40% of than. But China lithium battery production enterprise are mostly small private enterprises, from electrolyte production, is the production of anode materials to the diaphragm material production, and then to power management device of production, have relatively large technical barriers /

Now the “did” the phenomenon is very common, and this led to the industry chain to pull too long, difficult to ensure the quality, safety and service life. And, from the point of view of the waste treatment, the home of lithium battery electrolyte of main component is six fluorine phosphoric acid lithium, its polluting some times higher than the dry, if processes is not good, and will be of water, ecological system in caused by the destruction of the immeasurable. A senior professionals said recently lead-acid battery to be valued, mainly because the recovery, environmental protection, and after sales or lithium battery is difficult to recycling.

Electric car batteries development started more early, although through the test of the enterprise, more than 100 are able to get on the test, but very few. This is the lack of national unity evaluation system, evaluation standard mess and low threshold be caused.

The Bangkok post reports, China suntech solar battery power limited company plans to invest $20 million in Thailand assembly enterprises set up solar battery, hope to get the new government policy support of Thailand. Reports say, suntech company is the world’s largest solar cell manufacturing enterprise, this year it is forecast to output value of $3.5 billion, and Thailand market this year is expected to more than Australia, become the enterprise in the largest market in the asia-pacific region. At present, the company is with Thailand BANGCHAK suntech cooperation company to build a 38000 mw solar power projects expected this year, can be put into operation in November. BANGCHAK company President thought, and set up solar battery assembly enterprises can bring new green to Thailand jobs and reduce solar cells, and he called for a TaiZhengFu finished product imports come as soon as possible new renewable energy development policy, including improving solar power of the upper limit of procurement.

U.S. researchers in the new issue of “Journal of the American Chemical Society,” the said, they have developed a safe, effective method to extract and store hydrogen for fuel battery, promote the use of hydrogen to remove the obstacle.

Responsible for developing this technology, Assistant Professor University of Southern California Travis Williams said: “We have found a chemical extraction methods and storage of hydrogen. This method can be done to extract from the gaseous ammonia borane hydrogen, then converted to gaseous hydrogen stored ammonia borane complete the process, which is made ??in the field of hydrogen storage breakthrough has practical significance. ”

Ammonia borane is a non-toxic compounds, high hydrogen content. Earlier this year, Williams’s research team has developed from ammonia borane method of extracting gaseous hydrogen, but the drawback is not enough hydrogen release, and once after the release of hydrogen, it is very difficult to be recycled .

Now, Williams and his colleagues to the core of ammonia borane developed a catalyst system, can release enough hydrogen, making it an effective source of hydrogen. And the boron hydrides and metal hydrides as the core of the catalyst system is different is that this catalyst system is stable in air, light, and can be reused.

Currently, researchers are applying for a patent related to technology.

Williams predicted that: “the near future, small motorcycles, large aircraft, this technology can be applied.”

Hydrogen fuel battery does not release carbon, is considered an environmentally friendly product. As oil resources are becoming scarce, prices become increasingly expensive, scientists around the world had begun to explore the use of early development of hydrogen from fossil energy alternatives methods. However, gaseous hydrogen is difficult to store and transport. Currently, the market application of hydrogen fuel battery vehicle using high pressure or low temperature generally is stored not only costly, but also a security risk. “If the car filled with a full tank (hydrogen gas), in the event of an accident, damage to storage devices, it can be in big trouble.” Williams said.

September 16 morning, according to gaming news site Eurogamer, Sony PlayStation Vita (hereinafter referred to as “PS Vita”) of battery life 3-5 hours.

Sony said, PS Vita battery life of the game in 3-5 hours. If it is in standby mode, video playback battery life to 5 hours music playback battery life to 9 hours. Battery is exhausted after a charging time of 2 hours and 40 minutes.

In addition, PS Vita will be shipped with the USB cable, AV power adapter, etc., 4/8/16/32GB memory card sold separately.

Japan’s Showa Shell owned subsidiary of Solar Frontier plans to begin mass production in the second half of 2012, with a high photoelectric conversion rate of the CIS thin film solar cells, the conversion rate will reach 13-14% (fingerprints group conversion rate; same below). Reported that, Showa Shell’s current production of CIS thin film solar cell conversion rate was 12.2%, compared with the current mainstream crystalline silicon products 1-3 percentage points lower, it is produced by the Showa Shell conversion rate to be close to crystalline silicon solar cell products , to expand sales volume, improved solar cell business profitability.

According to reports, Showa Shell plans since the second half of 2012 will have an annual capacity of 900MW, “Miyazaki 3 plant (plant-rich country),” another production line to produce high conversion rate of the product. CIS solar cells is a form of Cu (copper), In (indium), Se (selenium) as the main raw material for thin film solar cells, whose main feature is the cost of price changes from silicon, and in some cloudy or panel shadow can still generate electricity.

1、Lead-acid batteries

Lead-acid battery as a relatively mature technology, because of its low cost, high-rate discharge and can still only available for mass production of electric vehicle batteries. Beijing Olympic Games, there are 20 lead-acid battery electric vehicles, transport services for the Olympic Games.

But lead-acid battery energy, specific power and energy density are very low, as a power source (600,405, stock it) of the electric car can not have good speed and mileage.

2、Nickel-cadmium batteries and nickel-metal hydride battery

Although the performance is better than lead-acid batteries, but contains heavy metals, abandoned after use will pollute the environment.

Nickel-hydrogen battery has just entered the mature stage, is the hybrid vehicle battery systems and is the only commercial real validation, large-scale battery system, the existing hybrid battery market share of 99% nickel-hydrogen batteries, commercial representative of the Toyota Prius. The world’s major automotive battery manufacturers are Japanese PEVE and Sanyo, PEVE Global Hybrid-powered cars accounted for Ni-MH battery with 85% market share, currently the main commercial hybrid vehicles such as Toyota Prius, Alphard and Estima, and the Honda Civic, Insight etc using PEVE nickel-hydrogen battery. In China, Chang’an Jie Xun, Chery A5, FAW Pentium, Grand Hyatt and other GM-brand vehicles have been run in the demonstration, they are also used in nickel-metal hydride batteries, but batteries are to foreign buyers, domestic nickel-metal hydride battery in the car use is still in development stage match.

3、Lithium battery

The traditional lead-acid batteries, nickel cadmium batteries and nickel-metal hydride battery technology itself is relatively mature, but they are used in automotive batteries as a power then there is a big problem. Currently, more and more car manufacturers to choose energy lithium batteries as a new car battery.

Because lithium-ion battery has the following advantages: high voltage (the hydride nickel-cadmium batteries – nickel batteries 3 times); than the energy of large (up to 165WH / kg, nickel-hydrogen battery is 3 times); small; light weight ; long cycle life; self-discharge rate; no memory effect; no pollution.

At present, many well-known car manufacturers are working to develop lithium battery powered vehicles, such as the United States, Ford, Chrysler, Toyota, Japan, Mitsubishi, Nissan, South Korea’s Hyundai, France, Courreges, Ventury and so on. The domestic auto maker BYD (002,594, stock it), Geely, Chery, Lifan, ZTE and other car firms also have their own hybrid and pure electric vehicle powered by lithium batteries.

4、Lithium iron phosphate battery

Lithium iron phosphate battery is a lithium battery, its energy is less than half of lithium cobalt oxide, but its safe, can reach 2000 times the number of cycles, discharge stability, cheap, a new car with power options.

BYD’s “iron battery”, the industry believe that it is more likely to lithium iron phosphate.

5、Fuel cell

Simply put, fuel cell (Fuel Cell) is a way to exist in the fuel and oxidizer in the chemical energy directly into electrical energy generating device. Fuel and air are sent to the fuel cell, electricity was wonderfully produced. From the outside, it has positive and negative, and electrolytes, such as a battery, but in fact it can not “reserve power” but a “power plant.”

The research firm said: “Three quarters of Japanese companies is expected to regain lost ground, but the higher yen, the won falling under the influence of factors such as competition is very tough.”

Next year, Germany’s Schott Solar will expand its product line by introducing a new high-performance solar modules, it has attractive looks and impressive performance. This component called Schott PERFORM Mono is based on a unique new battery technology to create world record: the world’s first efficiency of 20.2% 6-inch solar cells.

Schott PERFORM MONO has up to 280 watts of maximum power, and plans to the second quarter of 2012 in Europe.

“Schott PERFORM Mono is that Ming Xiaote company’s product development and product management, how to work together to promote the best example.” SCHOTT Solar’s director of product management Stefan Hergott said. The company became the world’s first 156 x 156 mm, 20.2% of high-efficiency screen-printed silicon solar battery manufacturers. SCHOTT PERFORM MONO so that the research breakthroughs into practice.

SCHOTT Solar emphasized that this component of the Italian PV market is more favorable, because there’s a higher tariff. SCHOTT Solar’s new products will be in Hamburg, Germany’s EU PVSEC show appeared the first time, the time for the September 5, 2011 to 9, the venue, booth A37 in Hall B5.

Schott said that not only the value of the product data sheet is to attract attention, but it looks very attractive. “It looks very good, especially the black silicon cells plus black borders.” Furthermore, it resistant to weathering performance, whether it is exposed to wind, rain, snow and ice (based on IEC standard 5400 Pascal pressure and suction load test), it can withstand the test of many years. Glass thin-film modules with all the same, SCHOTT Solar will provide 25 years of quality assurance.

Recently, the Chinese Academy of Sciences, Qingdao Institute of Bioenergy and Bioprocess Bionic Energy Systems Team Leader, Chinese Academy of Sciences “Hundred Talents” was selected by Cui Guanglei researchers, etc. in storage battery electrode materials research has made a series of important progress. Developing high-performance energy storage battery electrode materials is one of the core scientific research.

In general, the energy storage battery (lithium-ion battery, for example) there are three main dynamics: lithium-ion in the electrolyte in the transfer process; lithium-ion electrolyte and the electrode surface in the transition process; lithium-ion electrode material in the chemical diffusion process (Figure 1). Among them, the third process is a decisive step. In addition, this process must meet the diffusion limit, the solid electrode materials in lithium ion in the diffusion time (τ) and diffusion length (L) proportional to the square, that is: τ = L2/2D (D is the diffusion of lithium ion coefficient). When the electrode size becomes smaller, due to shorter diffusion path, the electrode materials in lithium ion diffusion in less time, making the electrode material rate performance can be improved.

Cui Guanglei team also solid with the German Max Planck Society, and colloidal metals by the Joachim Maier Professor, Antonietti Markus Professor cooperation mechanism in lithium storage materials based on in-depth study of the use of carbon nitride template method to design a the new Ti-VN / C nano-composite materials, the internal build a multi-phase interface. The kinds of materials show good interface properties of lithium storage in the large current, the material also showed good rate capability (ChemPhysChem 2010, 11, 3219-3223).

Research has been a major research project of Science and Technology (973), National Natural Science Foundation, Chinese Academy of Sciences “Hundred Talents”, Shandong Province Outstanding Youth Fund and other support for the project.

Some friends say that lithium batteries do not strictly charge and discharge, as used with the charge like, this approach is wrong. According to Russian experts, the best use of the battery once a month when it is the depth of discharge, that is, the battery’s remaining power is used up, then a full charge, three times, so that the battery performance can be sustained .

In general, the life cycle of a lithium battery can be 300 to 500 charge-discharge. Even if you do not hold the battery, lithium battery life is also just come to an end in two to three years. In order not to lose the battery prematurely role in normal use should be possible to observe the following principles:

1、to avoid complete discharge, and often for lithium batteries. Repeated arbitrarily charge of the lithium battery damage is very small.

2、will need to set aside to save the battery in a cool place, remember not to put in the refrigerator. Avoid placing them in hot car, such as stored for long periods, the battery charge to 40% after the placement.

3、 No need to purchase spare lithium batteries for storage, so this is actually a waste of battery.

Battery is used to use, as long as attention to proper use and storage methods, there is no need for excessive care, make it possible for us to do the “contribution” is the most important.

Solar battery market will reach back in 2015 12.3 billion. Backplane technical barriers, to participate in small, strong profitability, PVF film, PET film and EVA film critical materials gross margin over 40%. Meanwhile, back about 3% of the cost components is expected by 2015 the global market size of crystalline solar back up to $ 12.3 billion, has broad prospects for development.

China, as the largest producer of solar modules, solar energy back to the Chinese import substitution industries to provide a broad market, the future backplane and growth opportunities facing the industry related material. The future development of space solar power industry is huge, but considering the decline in subsidies in Europe and China, the weaker elements of competitive advantage, to give back and related materials, solar battery industry, “cautiously recommended” rating.

Since 2007 China has been four years of solar battery module production in the world. 2010 China production of crystalline silicon batteries 8.5GW, thin-film battery products 0.5GW, solar battery production accounts for about 50 percent of global output. Based on the current status and future capacity expansion plans, expected future share of domestic solar battery to further expand it back for the domestic solar industry with a broad room for growth.

Back in the solar industry, the highest fluoride content of membrane technology, mass production of short-term domestic enterprises still more difficult, and in the EVA film, PET film, back and other areas, domestic enterprises have begun to take shape, the future is expected to be more fast development and the progressive realization of import substitution.

Stock catalyst: the global solar energy industry than-expected growth, including non-European countries launched substantial subsidies, the global installed capacity upgrading, China accelerated the pace of import substitution industrialization back.

Key risks: global installed solar capacity is less than expected decline in demand; the domestic industry, import substitution back slower pace of the entire industry slowdown; back some segments of the industry in rapid expansion of production capacity, intense competition lead to profit decline
