China News Network, June 6 (Zhongxin Financial Reporter Ge Cheng) In recent years, with the rapid development of new energy vehicles, China's power battery industry has embarked on a different development path in terms of technology, industry and business model. In the current increasingly fierce competition in the industry, cutting-edge technological innovation is the "key to victory". How to seize opportunities in technological research and material innovation and accelerate the construction of a new industrial ecology?

On June 6, at the "New Generation Power Battery and Prospective Technology Theme Forum" hosted by the Sichuan Provincial People's Government and the Ministry of Industry and Information Technology, and jointly organized by the Equipment Industry Development Center of the Ministry of Industry and Information Technology and Academician Ouyang Minggao Workstation, academician experts and enterprise technology leaders jointly gave speeches, discussed and shared experience, and jointly made suggestions for the further development of the industry.

"Today, the entire industrial chain of China's power battery industry has achieved leapfrog development from domestic to overseas, and has become an important force leading the world." According to Huang Xiaowei, academician of the Chinese Academy of Engineering and director of the National Engineering Research Center for Rare Earth Materials, technological innovation is the first thrust of industrial take-off and the top priority of enterprise development. It is necessary to increase investment in basic theoretical research and original innovation to provide a steady stream of forward momentum for the development of the industry.

However, she also stressed that in the process of technological innovation, it is necessary to be both far-sighted and down-to-earth. Specific to industrial practice, it is necessary to consider the product cost and business model of the whole life cycle. Technological breakthroughs should be organically combined with product landing, strengthen collaborative innovation in the entire industrial chain, and accelerate the commercial landing and transformation of scientific and technological achievements.

At present, solid-state batteries have become an important development direction of a new generation of power batteries. Sun Xueliang, a foreign academician of the Chinese Academy of Engineering, analyzed the opportunities and challenges facing the development of solid-state batteries in the keynote report "New generation of power batteries and forward-looking technology". In his view, solid-state batteries have certain advantages in terms of safety and energy density. The industry should strengthen cooperation between production, academia and research in this field, further strengthen basic R&D and innovation, and attach importance to patent layout.

In the production of power batteries, technological innovation also plays a crucial leading role. Wu Kai, chief scientist of CATL New Energy Technology Co., Ltd., said that safety and energy density are the two key indicators that everyone is most concerned about. In order to maintain the technological leadership of the industry, we need to look further. The core of the next generation of power batteries is to solve the problem of energy replenishment time, and whether the system of the battery pack can achieve theoretical effects at low temperatures still needs data testing.

"We need to find an entry point to promote platformization to judge future trends." Yang Hongxin, chairman and CEO of Hive Energy Technology Co., Ltd., mentioned in his speech that from the perspective of unity and platformization, short knife iron lithium + ternary large cylinder is a very good solution, taking into account both cost and charging efficiency, or will become the mainstream direction in the future.
