“The batteries, including free” may still remember that after receiving a new toy on the side of the box these words to you poured cold water? Grow up, our high-tech “toys” have become increasingly complex and fascinating. However, they are Laptop battery engine works has not changed.

 

If so Mody?

 

Smart Grid (SmartGrids), hybrids, renewable energy, environmental technologies are hot, but behind the scenes, chemists and engineers are working to reduce the environmental impact of the battery. Recent hydroxy-nickel oxide, phosphate-olivine-type lithium iron nano-lines, nickel, lithium battery breakthrough chemistry technology should make tomorrow a variety of digital products, but to give up a lot of problems a long history of alkaline / manganese dioxide batteries AA.

 

Hydroxy-nickel oxide (NiOOH or NiOx) batteries are available for several years, similar to alkaline batteries, but the nickel anode function to generate a higher voltage (1.7 V, 1.5 V alkaline batteries). NiOx batteries are typically used for high power applications (such as digital cameras or portable gaming products), said to provide the equivalent of twice the duration of alkaline batteries. However, the remote and other light duty applications, NiOx battery life with alkaline batteries fairly.

 

First, the recent Sony lithium-battery technology of ion variants of marketing. The technology developed by U.S. researchers, using olivine-phosphate lithium-type iron (LiFePO4) as negative. Sony, the new anode material of a resistor is said to minimize the patented combination of particles to reach the design output 3.3V, 1800W/kg power density of the rechargeable battery design, with a long life In 2000 the charge / discharge remained after the initial capacity of 80%. The battery has a capacity for fast charge (30-minute charge 99%), and use to maintain a stable discharge voltage.

 

The VGP-BPS9A/B battery has been applied to some of Sony’s powerful tools and practical applications received positive feedback.

 

The first patents LiFePO4 technology JohnGoodenough University of Texas and his team have achieved in 1996. LiFePO4 as an oxide of lithium cobalt solution and structure of lithium manganese oxide such as lithium-ion battery rate discharge is low, short life cycle of a compliance program has been designed.

 

LiFePO4 material is very stable, scientists think it may be used in consumer applications, from mobile phones and gaming products, rechargeable batteries in electric vehicles and other large applications. (Coming Chevrolet Volt with 220 cell lithium-ion batteries).

 

LiFePO4 olivine structure allows deformation of the truss structure, smaller than other cells, leading to better discharge process. Therefore, the material life cycle very long, LiFePO4 has shown excellent shelf life. It can tolerate oxidative and acidic environment.

 

Security in the VGP-BPS9/S battery, the structure of LiFePO4 battery to 300 ° C to 500 ° C, high temperatures can remain stable, can withstand up to 700 ° C. In these extreme temperatures, and a lithium others will crack or even explode.

 

LiFePO4 fast charge, long life characteristics contribute significantly to protecting the environment. Car-Power LiFePO4 batteries will be used to get a load more in the car, wish to introduce products to compete with car manufacturers Volt may be interested.

 

Nanowire battery becomes a prospect for a solution

 

Another promising line of technology of lithium batteries is the nano-batteries to cover the battery stainless steel cathode lithium silicon nanowires to replace the traditional graphite anodes. Silicon can store ten times more lithium than graphite, so that power density has increased significantly. The total mass of the battery to reduce the surface area increased to allow faster load / speed.

 

The VGP-BPS9/B battery using the cathode surface covered by the line of silicon steel contraction / expansion of output power. Charging process, the silicon-ray absorptiometry in charge of the lithium atoms, the expansion occurred; discharge process, the line of silicon lithium-ion batteries being sucked, the linear shrinkage of silicon.

 

Under the electron microscope of silicon nanowires in the absorption of lithium before (left) and after (right) pictures. Network was extended to four times the normal volume, there is no damage.

 

The conventional silicon and simple positive studies, which began over 30 years. Scientists then decided to abandon silicon because this material easier to mobilize when the absorption of the division of lithium, damaged, cathode capacity is low enough to support further research.

 

Researchers at Stanford University was used to determine the problem stems from the shape of the silicon material.

 

The current method for a diameter of a thousandth of the thickness of nanowires paper tree. After the nano-size lithium-ray absorptiometry, was extended to four times the state standard, but will not break or damage the cathode of silicon.

 

Researchers VGP-BPS13/S battery nanowires are looking for an anode material is adapted to match with silicon net charge of positive / discharge capacity, to fully demonstrate the technology of the density of energy storage advances outstanding. Stanford University assistant professor of materials science and engineering, leading the team to develop this technology CRT YiCui, they think that after five years nanowire lithium-ion rechargeable battery technology, can achieve full commercialization.

 

Several technologies for more than just the start, with in-depth study of the continuation of the battery, electronics, players can expect the battery life is more than a toy’s life that day there.

Digital battery / No Comments

While the economic transformation of China, adhere to the concept of scientific development, take the path of sustainable development into the development trend of Chinese companies. The basic requirement of scientific development concept is a comprehensive, coordinated and sustainable demand for sustainable development, environmental protection property. Therefore, production of pollution, fresh produce, development of eco-industries is to implement the scientific concept of development to go.

 

New Leader VGP-BPS8 Battery Co., Ltd. breaking technical difficulties, the invention of the world to fill gaps in mercury free button batteries, we adhere to the strategy for environmental protection in China and the world has d ‘immense contributions.

 

As a farm producer, the battery industry in China in 1995, held the world production of over half of the battery. However, because of the battery prior to contain excessive levels of mercury, which we usually refer to the mercury, causing environmental pollution and poisoning, which makes security issues battery life stood out.

 

Ms. Cheng, Zhejiang Xianju use a certain brand of soft bed even contains a large number of highly toxic substances – mercury, lead to the family of three with a severe mercury poisoning, Hebei, Baoding several students play mercury due to incidents of mercury poisoning caused people to hit the alarm bell buoy in the prevention of mercury poisoning; 1956 Minamata disease in Japan incident occurred in the Gulf have been made by the large-scale contamination of a large number of dead fish, local residents place on a strange disease. And the main culprit is VGP-BPS8A mercury.

 

The dangers of mercury poisoning serious consequences on human security. Studies have shown that mercury-free batteries is very important for humanity, because products containing mercury, including the threat of mercury batteries inside the health of people around the world. Mercury on the brain and nervous system toxin interfere significantly with normal nerves, pregnant women and children are at high risk. Fetus or infant exposure to high doses of mercury can cause mental retardation, cerebral palsy, hearing loss, or loss of vision. Even exposure to low doses of mercury, may also affect the healthy development of children, it may enable them to attract attention, action coordination, language skills, visuospatial, and memory problems text. For adults, a chronic mercury poisoning can cause memory decline, seizures, vision loss, and the hands, feet means paralysis, and fertility and the devastating effects of blood pressure. Increasing evidence shows that exposure to mercury may increase heart disease.

 

And because the battery of a high frequency of use and universality, making the threat of mercury-containing batteries become more evident. It is reported that a New Zealand-style micro-mercury alkaline batteries can be contaminated by water is 600,000 liters, equivalent to the amount of water, the life of a person. Although in 1995 the United States and Europe have issued a ban on the sale of mercury-containing VGP-BPS8B batteries with relevant and clearly defined, alkaline zinc-manganese batteries can not be added to the mercury content Mercury is more than 0.0005% of the total number of cells, but because the world has no technology can produce mercury free button batteries, button cells can not allow the mercury content is more than 2% of the total mass of the battery.

 

The export volume of China’s battery has been for several years have represented more than half the total battery international. According to international standards, in 1997, the Chinese government issued “on the limitation provisions of mercury batteries and other series of measures. The Chinese battery in a short space of two or three years, research on the adoption of technology to address mercury, zinc-free alkaline manganese batteries in question. However, the face of ever increasing amount of button cells, the world without a corresponding solution.

 

In other countries, more than a decade in Japan and the United States, Europe and other well known manufacturers of mercury-free VGP-BPS9A batteries, mercury free button cell surprised by a large number of studies. However, there are technical problems are not resolved, there is no one company can successfully produce mercury-free alkaline button cell, resulting in the global market has been the use of mercury-containing button cell alkaline. Coin 1 billion each year by the production and use, so that China and the rest of the world, people still face the risk of mercury exposure.

 

The problem with the new invention Qing Li Dade can be resolved. After years of research and development testing, the new head of R & D Team in 2000 mastered the art form, using a layer of iron tablets add electroless nickel and copper, indium or the tinning and success will be mercury-free alkaline button cells that China and Hong Kong patent licensing and patent applications processed in other countries. China Battery Industry Association, said the mercury key industry free cell battery, the world is a “historical” of technological progress.

 

Products New Leader Battery Co., Ltd. was founded in 1983, the company mainly engaged in the production of button cells are based mainly exported to the United States and other EU countries, some European and American for mercury free batteries have become more demanding, the new leader of mercury free button batteries which have enormous potential, and so R & D team specialized organizations of mercury free button batteries have been studied.

 

Because of this advanced technology for the first time the problem of mercury in button cells, avoiding the appearance of the tragedy of mercury poisoning, therefore protecting the global environment has made a significant contribution. To this end, the U. S. Natural Resources Environmental Association Special Industries Association of China battery, sent a letter to congratulate the company developed the new leader mercury battery-free for the cause of protecting the global environment a major contribution.

 

Unfortunately, due to competition, and often repeatedly mentioned the valid application, the Patent Review Board for eight years to three patents on the new leader to make the decision null and void, and now has a new leader Court of Appeals for the third militant hard.

Digital battery / No Comments

In the new energy vehicle development in countries and regions around the world have been based on their assessment of different options, research the appropriate technology and Laptop battery development and to encourage support for taking a different strategy. In the current situation as a whole, Japan and the United States and Europe has focused on lithium batteries and fuel cells, but our country to take into account the resources and the maturity of technologies, the accent newly released policies on the promotion of nickel-hydride batteries in metal.

 

Ni-MH battery to become the object of political support China’s current

 

In our letter of the Department of June 25, the “new energy automotive manufacturing companies and the rules of access management products,” the vehicle, according to new energy vehicles, systems and key deadlines assembly technology, the degree of perfection of the national and industry standards, and industrial degree of difference will be divided into initial phase where the development period, three different stages of maturity of the technology and give Management classified.

 

According to state regulators, the home-products only in the production of small BTP-43D1 volumes, and only in approved areas, scope, duration and conditions of model runs, and the operational status of all products for real-time monitoring, product development phase allows the mass production only the approved area, scope, duration and conditions of sale, use, and at least 20% of sales of products running in the real-time monitoring, mature products and conventional products for the automobile, “the automakers and ad management product even in the sale and use of the same products with conventional automotive .

 

This means that in China, December 31, 2010, equipped with lithium batteries and hybrid electric vehicles will be limited to the sale and use areas, use nickel-metal hydride battery and hybrid electric vehicles can be sold and used across the country.

 

Experts believe that the reason why countries are now central to the development of lithium nickel-hydride batteries, metal, the main reason is that the nickel-hydride technology of metals of the battery is more mature than the Lithium, the most abundant mineral resources, the future of new energy vehicles will track better access to the advertising phase. “Ni-MH – Lithium-Ion Dell Inspiron 1525 battery- fuel cell,” Industrialization Path

 

In the three commonly used types of car batteries, batteries lead acid to cause serious pollution of the environment has long been out of the consumer applications, nickel-metal hydride batteries, although the marketing of the integrating the moment, but key indicators of laboratory data were lower than lithium batteries, and the basic theory, there is no room for; lithium despite superior performance, but still can not be guaranteed safety and the relatively high costs have also affected its business.

 

Experts predict that the new energy vehicles will be in the “Ni-MH – Lithium-Ion battery – fuel cell” industry-oriented development path. From the trend of development and rates, and short-term performance can be achieved only with nickel-hydrogen batteries, nickel-hydride technology of metal drums since the most mature in the next three years, will remain the mainstream new energy vehicles, followed by nickel-hydride technology of metals of the lithium and iron phosphate, hydrogen fuel cell-thirds of the world, 5-year lithium batteries and will be gradually replaced by fuel cells. Battery giant Panasonic and Sanyo also found that lithium-ion hp 346970-001 battery can be replaced within 2 ~ 3 years, nickel-hydrogen batteries, mainly due to cheaper nickel-safe hydrogen batteries, has reached high production wide. Lithium batteries also need to continue to research topics such as security, so take time business.

 

According to economic analysis of Japan Fuji mainstream nickel-metal hydride batteries will be able to continue until 2011, but after 2011, Li-ion battery will gradually erode the market share of nickel-hydride batteries, metal The agency predicted in 2009 Ni-MH rechargeable battery market vehicles world-wide as the previous year by 23.7% to ¥ 92,000,000,000, but the 2015 Ni-MH rechargeable battery-vehicle market will be reduced to ¥ 55,000,000,000 .

 

Market demand for nickel-hydrogen batteries to save 2-3 years of rapid growth in

 

Nickel-technology hydrogen fuel cell, and the industry chain to determine their maturity will be a period of time with the coexistence of lithium batteries, lithium iron phosphate cathode material for lithium batteries allows the emergence of performance and cost advantage has been achieved, but stability of the capacity gaps and lack of verification of actual operation continues to be a part of the new energy discourage automobile manufacturers; In contrast, nickel-hydrogen VGP-BPS2B batteries have gone through many years of fighting, technical and industrial chains are quite perfect, in a short period of time can be formed on the vehicle stability and supporting capacity and can therefore still be a period of time in the new energy vehicles and widely applicable.

 

According to industry estimates, the market for nickel-hydrogen cell is still expected to get 2-3 years of rapid growth over the next 2-3 years, “10 City 1000″ program, the growing popularity of hybrid cars and export markets overseas for nickel and other factors make hydrogen market demand from the battery to strong growth, and when the nickel-hydride batteries, metal and batteries Lithium is still Nanfenbozhong when the nickel-hydrogen batteries will usher in a short period of rapid growth.

 

Among them, China has launched a “10 City, 1000″ How to get the first batch of nickel demand hydrogen battery market. It is estimated that in “10 City, 1000″ program, about 3200-4000 vehicles, new energy vehicles (including buses and cars) using Chinese-made nickel-hydrogen batteries in three years , bringing a total of about 3.5-4.4 one million kilowatts-hour nickel-hydrogen toshiba PA3399U-2BRS battery needs.

 

Together, both domestic demand and exports weakened in 2012 after the nickel-hydrogen batteries are gradually replaced by lithium batteries.

 

Maintaining the pace of R & D policy

 

In the production of automotive battery business in China with a production capacity of nickel-hydrogen batteries have represented the majority of companies, including Chunlan Group, Ke-Li Yuan, the Torch High Technology, Hunan Shenzhou share Kane etc., which Chunlan Group is the nickel-metal hydride HEV battery power technology, leading market shares in a leading position in the Torch High Technology and Hunan Shenzhou possessed a certain amount of technical base and position market.

 

As for the lithium battery, most domestic manufacturers are not capable of mass production, but the planning of the corresponding production has been implemented, it is expected after 2010 are capable of mass production.

 

Experts believe that technological advances, prices for cars in China and business related to the battery in addition to promoting the industrialization of nickel-hydride batteries, metal, more attention should be some of long term, to devote resources to research and lithium battery development, and maintaining fuel cell monitoring techniques to fill a broader energy market new car is ready.
