The morning of July 22, 2022 world conference on power battery professional BBS "global power battery forward-looking technology breakthrough" special BBS successfully held in yibin, BBS sponsored by the people's government of sichuan province, the Ministry of Industry and Information Technology, industrial development center of Ministry of Industry and Information Technology equipment to undertake together with the ming-gao ouyang academician workstation. Nearly 20 industry experts, including academicians, experts and scholars, entrepreneurs, gathered to share a high-standard industry event of power battery technology innovation and breakthrough for the live audience and the live audience.

Qu Guochun, director of Equipment Industry Development Center of Ministry of Industry and Information Technology attended the forum and delivered a speech. He pointed out that in the face of rapid technological change and industrial changes in the field of power batteries, enterprises are increasingly competitive. In order to obtain long-term competitiveness, enterprises should take technological innovation as the root of development and the source of vitality. The more forward-looking, leading and disruptive the scientific and technological innovation, the more valuable it is. However, when it comes to industrial practice, the cost and commercialization must also be considered. From the perspective of the industry as a whole, high-quality development not only depends on high-level international openness and cooperation, but also requires close cooperation and coordinated development of the whole industrial chain.

Focus on battery safety and technology innovation

BBS by tsinghua university vehicles and carrying dean jian-qiu li as a moderator, invited the European academy of sciences, professor at the university of science and technology of China, chief scientist chin-hwa sun country "973" plan, the national inventors academy of sciences, professor at Pennsylvania state university professors, battery and energy storage technology research institute director wang, Wang Yu, chairman of Fu Neng Technology (Ganzhou) Co., LTD., Wu Kai, chief scientist of Ningde Times New Energy Technology Co., LTD., and Feng Xuning, director of the Battery Safety Laboratory of Tsinghua University, made keynote speeches.

The special report focuses on battery safety and next generation power battery and battery system technology.

Academician Sun Jinhua summarized and analyzed the forward-looking technologies, such as intrinsically safe power battery, very early fault diagnosis and accurate prediction technology of thermal runaway, and intelligent integrated safety prevention and control technology.

Academician Wang Chaoyang introduced the all-climate battery, fast-charging battery and heat-resistant power battery in the form of video speech. He believes that LiFSI salt has good thermal stability and may become the mainstream development direction of the industry in the future. Viscous, non-combustible electrolyte will also become the mainstream development trend. He believes that the development trend of batteries in the future is from liquid cooling to all solid CTP, no liquid, no pump, no leakage with extremely high compactness, reliability, safety.

Wang Yu, chairman of Fu Energe Technology, focused on the introduction of Fu Energe technology "1+N" soft pack semi-solid battery technology, cell energy density of more than 330Wh/kg, with high safety, low temperature resistance, high power, long life and super fast charging characteristics. Wu Kai, chief scientist of Ningde Times, focused on the new material of M3P battery, sodium ion battery, kirin battery technology and integrated intelligent EV chassis technology. Feng Xuning, director of the battery safety laboratory of the School of Vehicle, Tsinghua University, believes that at present, whether it is power battery or energy storage battery, there is a problem of uneven safety technology level, and all enterprises still need to improve their awareness of safety responsibility. At the same time, he analyzed the progress of battery safety prevention and control technology from the four dimensions of essential safety, standards and regulations, active safety and passive safety, which provided important reference and guidance for enterprises.

Technological innovation leads the future of the industry

In order to strengthen exchanges, the forum set up a round table dialogue session, and invited Wang Yan, director of Defective Products Management Center of the State Administration for Market Regulation as the moderator. Dialogue include xiao peng car He Tao co-founder, senior vice President, Martin new energy co., LTD., the CTO wear vigorously, saic gm wuling automobile co., LTD., the CTO Shao Jie, wei Zeng Shizhe system for car battery research and development vice President, Beijing branch power technology co., LTD. The chairman gave, yibin day the original group chairman, vice President, guangzhou lithium Wang Zhengqiang, etc.

From the perspective of power battery technology innovation, industry experts and technical experts will discuss the opportunities brought by technological progress for the development of new energy vehicle industry. Lithium iron phosphate and ternary battery have their own characteristics and rapid development. The future development of lithium iron manganese phosphate or M3P materials, as well as sodium ion batteries suitable for walking out of the car deserve attention. At the same time, it is the only way to greatly improve the safety performance of power batteries by strengthening technological research and innovation in battery chemical system, battery materials, cell design, technological process, PACK and management system. Strengthening the construction of automobile service network and after-sales quality assurance service, applying intelligent technology, providing after-sales active service and intelligent after-sales service is an important link for the development of high quality industry.
