Batteries are 5-10 years for breakthroughs in the development of new energy vehicles and life gate technologies

The core components of new energy vehicles have many technical and application problems such as high cost, high-grade materials relying on imports, short cycle life, low energy density, low level of design process, and lack of testing equipment. This is also the difficulty of industrialization of new energy vehicles. important reason. For China's new energy automotive industry, it should be based on batteries to plan the development of electric vehicles, increase the battery industry's norms and guidance, and speed up the construction of standard systems and testing and evaluation systems.

The battery decided that the Electric Vehicle Fate of Engineering Academician Yang Yusheng recently stated that “Battery is the first element that determines the performance of electric vehicles.” Regarding the 'Twelfth Five-Year' industrialization task, it is to use and improve the existing various batteries. Vigorously develop miniature pure electric vehicles. ”

Wu Zhixin, deputy director of the China Automotive Technology and Research Center, told reporters that in the past ten years, the energy-saving and new-energy vehicle strategies and national strategies of auto companies have not been fully coordinated, and the price and cost have become the biggest obstacles to the marketization of new energy vehicles. Among them, the battery cost price determines the fate of electric vehicles.

Zhao Bo, deputy director of the Department of Electronic Information of the Ministry of Industry and Information Technology, said that at present, the electronic control, battery, and motor fields of domestic companies still have great differences in meeting the large-scale commercial use of new energy vehicles. In particular, the battery problem of new energy vehicles, the existing battery technology, reliability, stability, and product cycle life is not long and other factors have affected the development of new energy vehicles.

According to Peng Hongbing, director of the Electronic Technology Division of the Electronic Information Department of the Ministry of Industry and Information Technology, the construction of the battery's standard system and testing and evaluation system is the basis for supporting the development of the industry, but it is currently a relatively weak link.

The breakthrough of the battery problem takes at least 5-10 years. The core components of new energy vehicles have many technical and application problems such as high cost, high-grade materials relying on imports, short cycle life, low energy density, low design process level, and no detection equipment. It is also an important reason why the industrialization of new energy vehicles has been difficult.

It is understood that at present, 50% of the major power battery products in China are exported, and in 2012, sales are expected to reach 4 billion US dollars. The top four domestic companies are Lishen, BYD, BAK, and ATL, which have a relatively high degree of aggregation, accounting for 36% of the domestic share.

Peng Hongbing said that in the future, the lithium-ion battery market in the consumer sector can reach nearly US$30 billion, and the market for the power sector is also close to US$30 billion, and the energy storage capacity may be even greater. "The forecasting agency has more data, and we are more rational, probably between 80 billion and 100 billion US dollars."

Although the market cake is huge, the key technology of the battery failed to break through, and the low energy density directly led to a fatal injury to the new energy vehicle's short range. It is widely believed in the academic community that new energy vehicles can be industrialized on a large scale when the energy density of a power battery reaches 250-350 Wh/kg. At present, the power battery energy density of various domestic technology routes is only about 100 Wh/kg.

“Some enterprises are eager for quick profits and are pursuing short-term profits. They are not sufficiently deep in their research; others include the level of key materials, equipment, etc., especially in relation to the power battery industry. Safety, reliability, etc. have not yet been implemented. More in-depth study. In addition, the standard detection system is currently relatively disordered." Peng Hongbing said.

The industry generally believes that breakthroughs in power battery technology will take at least 5-10 years. At present, the private consumption market environment is not yet mature. When selecting the technology route during the transitional period, battery manufacturers and vehicle manufacturers are each fighting to develop on their own, while the market mainly depends on the policy of “eating”.

Li Yao, general manager of Shenzhen Waterma Battery Co., Ltd. said: “Technology selection is not so absolutely important, and domestic companies are still unanimously inclined to make lithium batteries.”

Although battery technology requires revolutionary innovations, the domestic battery industry has seen a chaos of overcapacity and the backdoor concept of speculation. "The actual profit of the battery is very small. The investment of cell phone batteries is generally several hundred million to more than one billion yuan, but now it is less than 2 billion yuan to sell electric vehicle batteries. This is a market environment. Large-scale investment), the capacity investment can not be left over?” said Li Zhongdong, chairman of Henan Huanyu Group.

“Impression is a problem in the corporate world, and the government and the academic community also have this problem.” Chen Quanshi, chairman of the Electric Vehicles Branch of the China Automotive Engineering Society, was blunt.
