Power battery white list coming back & Panasonic building a battery factory in China

That was Power battery Enterprise "white list" of a headache and a new version, but expected effect could face a big challenge.

A few days ago, RGL association, China's auto power The battery Industrial innovation alliance issued on the website the auto motive battery and hydrogen fuel cell industry interim measures for the administration of white list "(hereinafter referred to as the" management method ").

With the auto motive battery industry standard conditions issued by the Ministry of Industry are different, "management method" for the enterprise in the production conditions, technical skills, products, quality assurance ability and so on has made a clear requirement, but not specific production capacity of enterprises put forward clear requirements, at the same time also is not linked to new energy vehicles subsidies. White list as the indefinite system, at any time declare acceptance at any time.

RGL association, "management method" is to "auto motive battery industry standard conditions" the enterprise directory.

The personage inside course of study thinks, the relevant departments, issued the management measures for the main purpose is to regulate industry healthy development, but to achieve the desired effect and ground execution may also has many challenges.

In fact, in recent years, the government departments in order to promote the development of China's power battery industry, continuous issued multiple policy, but due to the rapid changes in policy and industry, intermittent shock power battery industry, let the battery enterprises suffering.

From the point of the market situation, power battery increasingly fierce market competition, market concentration, industry polarization is obvious. On the one hand is the age of Ningde dominance, with nearly half of the market share; On the other hand, a large number of batteries, small and medium enterprises faced with great survival test. At the same time, the new subsidy policy is greatly increased threshold power battery technology, improve product quality and technical level becomes the key to the battery enterprises participate in market competition, it also makes a number of smalls and medium-sized enterprises are faced with the risk of technology is not up to standard and be washed out.

In such a competitive situation, the influence of the "management method" and how binding, and if you can let the battery enterprises to accept and recognition, so far, are still a lot of variables.

Here is to see what is the new technology of lithium electricity industry this week and big events.

Panasonic or cooperate with Tesla again set up factory in China

According to foreign media reports, Panasonic company said a few days ago, is considering again with Lars cooperation, establish a super battery factories in China.

In 2017, Tesla confirms with Shanghai government cooperation in the establishment of local production base, but this should be at the end of 2017 announced plans did not take place as scheduled. At CES, Panasonic, Panasonic President Jin He Yihong said the company is currently considering for Tesla future Chinese battery factory production, production and factory is in Nevada state.

Tianjin He Yihong said, because the Tesla has plans to start the localization of pure electric vehicle production in Shanghai. Panasonic is also considering propulsion for the investment to Chinese factories, although not yet finalized detailed plan of batteries in China but Panasonic has considered the possibility of production of Tesla battery in China.

Comments: as motive power sources of Tesla's sole supplier, Panasonic perennial topped power battery shipments of the world's first title. But along with the rapid development of new energy automotive industry, Panasonic is in 2017 by the mingle age beyond relegated to the second, which makes Panasonic feeling the pressure. Under this situation, taking the advantage of Tesla plans to promote production of China, Panasonic has announced plans to build a super factory in China, purpose, or will be to provide supporting for Tesla, but it is possible that in order to open the Chinese market, under the subsidy TuiPo situation, Panasonic's competitive advantage further highlight, power battery enterprises in China or will face more severe challenges.

South Korea's new sodium ion battery anode to reduce costs by 40%

Recently, the south Korean school of science and technology (KAIST) claims developed copper sulfide anode sodium ion batteries, is expected to reduce overall production costs and improve your battery capacity, and lets the sodium ion battery toward commercialization.

KAIST Jong MinYuk of materials science and engineering and Jeong YongLee together to develop a suitable for sodium ion battery anode material, and in the test, sulfide copper anode loop is 1.5 times higher than the old material, the manufacturing cost are expected to more can be reduced by 40%.

Study also points out that through crystallography adjustment after copper sulfide, sodium can be put into the reaction space, test results showed that, compared with the lithium ions in graphite, copper sulfide sodium metal ions into ability is about 1.5 times higher, also can keep the initial capacity after 250 times charging and discharging cycle by 90%.

Review: is the current cost reduction of all power battery enterprise one of the most important work, reduce the cost of materials is a feasible path. But from the point of raw material cost, cost of power battery cathode material is the largest proportion, especially the ternary cathode material, the cost of anode materials can drop space is very small. South Korean court declared that science and technology to develop a suitable for sodium ion battery cathode material, is expected to make the cost can be reduced by 40%, the target might just an ideal.

Water-based zinc or will replace the battery The lithium battery

According to Moscow (news, U.S. researchers have developed a rechargeable water-based zinc batteries, not only large capacity, long service life, and safer, is expected to become the ideal alternative to the widely used lithium batteries.

The technology by the U.S. army researches laboratory and the national institute of standards and technology published in the journal of natural resources, researchers at the university of Maryland in a kind of new water and zinc-based batteries made significant breakthrough, or to use in the future mobile computers and other consumer products.

They use a new type of aqueous electrolyte, alternatives to traditional Lithium ion batteries Used in the inflammable organic electrolyte, greatly improved the security of the battery; And by adding metal zinc, and add salt in the electrolyte, effectively improves the energy density of the battery.

Zinc batteries, the researchers say, is a safe, and the production cost is relatively low battery, but low energy density, life is short, and thus are not perfect. New water-based zinc batteries will overcome the traditional zinc batteries these shortcomings, not only greatly improves the energy density of the battery, the battery life longer. And compared with lithium battery, water-based zinc batteries not only in terms of energy density with one, and much more security, there will be no explosion or the risk of fire.

Review: adopting new electrolytes replaces traditional flammable organic electrolyte, thus overcome the low zinc battery energy density, short service life of fatal flaw, also more security, this is obviously a solid-state lithium battery research and development train of thought. Also very honest, but researchers show that water zinc-based batteries can be used for mobile phones in the future the consumer products such as computer, this shows that the low energy density is still the short board, unable to meet the requirements of the electric car long range, for lithium batteries are never talked about.
