Development is hampered by technical bottlenecks of power batteries.

Nearly period of time, new energy vehicles under the support of policy in major cities nationwide, upstream industry is also under a lot of good.Top battery factories are the leading global production factories in China.Although the new energy automobile market led to the continuing boom in the battery industry, but whether it is a pure electric power battery, or hydrogen as fuel for fuel cell, at present there are still technically cost and durability of the challenge.

On November 10, the ministry web site, according to data released China's new energy automobile production in October 50700, increased 8 times.Is expected in the next two months, new energy automobile production per month, more than 50000 cars will also continue to cumulative production is expected to exceed 300000 cars in all the year round.Core parts industry experts predict that as the new energy vehicles, power battery market share will reach 38% this year, the capacity will be up to 50 YiAn, market demand of hunger is expected to ease in the second half of next year.

Since this year, as the new energy automobile market continues to boom, many enterprises has been clear about the power battery for the future development direction, increase investment, expand product lines, such as new plant phenomenon appear constantly, "power battery shortage" has been in the industry, the most obvious, is a severe shortage of supply of lithium battery grade lithium carbonate from earlier this year the price of 40000 yuan/ton rose to 70000 yuan/ton, and still hot.

China's auto industry to develop new energy automotive technology research center, director of research at a former pointed out that the current power battery industry mainly concentrated in four regions, respectively is: the pearl river delta, the Yangtze river delta, central plains and the beijing-tianjin region, has combined with nearly 20 billion yuan industry funding, nearly 15 GWH capacity and the power battery enterprises nearly 100.

Following the samsung SDI xian plant's completion, LG chem new energy battery project (phase I) in nanjing, on October 27, is expected to realize the mass production next year, annual output can reach more than 100000 units, the project is the world's largest electric car battery manufacturer of LG chem.Company plans to automobile power battery capacity from 2016 as the global 50000 electric cars to meet the 2020 200000 electric cars, increase 4 times.

According to China securities analysis, due to the electric car downstream demand, the power battery supply stage in China, according to a second line power battery manufacturer's expansion plans, the demand situation at least until the end of 2015.China power battery leading hin high-tech company in 2016 is expected to expand production capacity to more than 600 million Ah.Both energy storage andThe lithium batterySMW shows the three quarterly reports of the business,Power lithium batteryImplementation of several automakers batch supply, income is 65.49 million yuan, and in the same period last year have not related capacity.So far, the company has built in lithium battery capacity of 600 mw, and continues to release, is expected to be completed by the end of the year of 1200 mw of new production line.

"This year, power battery, battery materials are crazy, selling list to meet, no more to throw a lot of the funds, finally to the good times."Shanghai an incubation period of vc company focus on new energy investment manager.She predicts the future 1 ~ 2 annual capacity shortage phenomenon will continue.Company in 2008 invested in a battery project, due to current market hot, has begun to consider exit, above offer round round of potential investors.

The most sensitive sense of smell of capital, since the second half of this year, from time to time to see the listed company are looking for power battery related projects.And so is the secondary market, the new energy automotive industry chain is a rising stock market was the first to recover after the big adjustment of one of the main engine.According to statistics, since September this year rose by an average 33.54% battery plates, energy storage sector rose as high as 42.53%.

Due to high demand, high battery prices, the relevant company three quarterly performance bright eye.According to statistics, as of now, data of listed companies have released three quarterly reports, revenue grew 16.26% year-on-year in the first three quarters of the battery plates, net profit rose 63.25%, energy storage sector revenues than the same period last year growth of 18.32%, net profit rose 29.92%., one of the main lithium battery Shanshan shares when the rise of science and technology, the day his LiYe, hin third-quarter results are compared with the increase of more than 100% in the past Wanda, Shanshan soared about 341.28% shares.

Although the current new energy automotive battery industry demand, but the battery technology is still stopped in front of the new energy vehicles development a ravine.If the battery pack of pure electric vehicles, fuel cell electric vehicles, there are cost and the durability of the challenge.

Lithium ion batteriesGroup than can be significantly more than 0.25 KWH/kg battery system, has so far failed to achieve.So for mid-size car market, based on the lithium ion battery pack pure electric vehicle charging a single range of more than 300 kilometers could not theory, even if has a related products, the price also is the general consumers difficult to afford.

On the basis of in the lithium battery in the system, the current lack of stable electrode component and electrolyte materials, there is no guarantee that the oxygen in the process of charging and discharging cycle regeneration reduction rate of 100%.So future basic research and material development, for further verification has been carried out the feasibility of the lithium/oxygen battery.

Lithium/sulfur battery is difficult to obtain the ideal proportion of energy density, no matter adopt what kind of electrode material, lithium/sulfur battery can achieve more than the volume energy density is greatly less than traditional lithium-ion battery pack.In order to make the proportion of cells is competitive energy density, lithium/sulfur battery requires considerable capacity surface area (greater than 4 ma/cm2) and high sulfur content of cathode (> 60%).

In terms of specific volume energy density, lithium/sulfur battery unit completely than traditional lithium-ion battery pack.But consider the cost factor, lithium/sulfur battery may have certain advantages, because of increasing the safety of the life cycle and additional components (diffusion membrane, etc.) the price is relatively low.If the solid electrolyte interface was developed to prevent the electrolyte membrane continuously drains, application of silicon instead of lithium metal as the anode material, is likely to increase the energy density and to extend the life cycle.Lithium/sulfur battery silicon anode remains an open question, involving how compatible with lithium, lithium method including industrial feasible pretreatment process, or replace sulfur cathode with lithium sulfide.

In the past decade, the hydrogen fuel cells obtained the very big progress.Cathode are highly active catalyst concept of platinum use in each fuel cell car down to less than 10 grams.To take off the alloying technology processing and new types of platinum/alumina catalyst shows excellent voltage loop stability, reach the standard set by the U.S. department of energy.The challenge now is to put the advanced concept of catalyst with high durability of carrier materials together, so as to ensure that in the whole performance of the fuel cell vehicles use period.In addition, low platinum loading caused by the quality of the transmission loss also need to get more detailed understanding, to better reduce the loss.Fuel cell medium is one of the main challenges and explore the suitable for high temperature and low relative humidity environment material, help simplify system design, improve the thermal efficiency and to reduce the loss of the energy of the air compressor.

At present, the government support for new energy vehicles are mainly concentrated in the back-end sales, less investment, in the front of the research and development design, the "unbalanced" will cause the very big lag effect, this also is the current battery technology development can't keep up with market sales growth of the main internal cause.Don't break this "imbalance", the development of new energy vehicles would be like a "cripple" difficult to run fast.We should build a reasonable the top floor of the building, increase the technological innovation to strategic position, to make the new energy cars run faster and faster.
