New energy battery technology urgently needs to be broken

Wang Binggang said that research and development that can only be used in a random way can't solve the bottleneck of new energy battery technology and must rise to the national strategy.

Yesterday, the reporter learned from Wang Binggang, head of the supervision consulting expert group of the national "863 Project" energy saving and new energy automobile major project, that the Chinese Academy of Sciences and the China Nonferrous Metal Research Institute are conducting research on the next generation of power battery technology and discussing the formation of China's automobile power. Battery Research Institute.

It is reported that the main technical bottleneck restricting the development of China's new energy vehicles is the difficulty of battery capacity breakthrough, resulting in a short driving range, and thus unable to achieve the level of alternative to traditional fuel vehicles, and this is also a global problem. However, from the current news, Japan has gathered a number of universities and companies to conduct research on high-energy-density batteries. The target is to reach 300Wh/kg in 2015 (supporting 300km of battery vehicles); to reach 500Wh/kg in 2030 (replacement The level of the traditional fuel car).

Wang Binggang said that at present, the energy density of China's better lithium iron phosphate battery can be 100Wh/kg, and it can support 100 kilometers. At the same time, some battery companies in China are conducting research and development of next-generation batteries. They use ternary materials and modified lithium manganate, and have energy densities of up to 180Wh/kg, supporting up to 200 kilometers, and are expected to be industrialized within two years.

General Manager Shi Haijian of Universal Solar Energy, who has been engaged in the production of new energy vehicle power batteries for many years, admitted to the “Securities Daily” at the “2012 (3rd) China Electric Vehicle Industry Grand Ceremony” that new energy batteries are a high investment. Industry, and domestic new energy vehicles have just entered the commercial operation, the business model has not yet been profitable, although the company has injected Britain's Ou Rui Fund, but mainly focused on the current commercial applications of the broader lithium iron phosphate battery, for higher density The research and development of the power battery, the business is still a glass of water.

This is also what Wang Binggang is worried about. “Because there is a lot of R&D in zero-grid institutions, we are not leading the way in more advanced battery technology research and development, so we are still looking forward to the government's leadership and promotion and rising to the national strategy.
