Academician recommends that the state invest heavily in key technologies for lithium batteries

Yang Yusheng, an academician of the Chinese Academy of Engineering and the first institute of the Research Institute of Chemical Protection, recently said in an interview with reporters that although there are currently more than 100 car companies in China, the core components of China's electric vehicles are lithium batteries. The lack of production technology, a number of key materials rely on imports. Therefore, he suggested that the state should invest a huge sum of money to set up a major project for lithium battery research and development, and accelerate the pace of breakthroughs in lithium battery key technologies.

It is understood that the world's leading lithium battery technology in the United States has invested 1.5 billion US dollars for the development of lithium battery and battery parts manufacturing. However, our country still lacks corresponding investment. To this end, Yang Yusheng and the Lithium Battery experts Chen Qingquan, Chen Liquan, and Zheng Mianping, three academicians of the Chinese Academy of Engineering, submitted a report on the development of electric vehicles in China to the State Council. The report suggests that the state allocates RMB 2 billion to establish a major research and development project for power lithium batteries, which will comprehensively upgrade China's power battery production technology and achieve localization of diaphragms and electrolytes; overcome the battery module grouping technology, improve battery safety and consistency, and battery packs. The life span reached 1500 charge and discharge times. This will provide core technologies with independent intellectual property rights for lithium batteries for pure electric cars after 5 to 10 years.

Yang Yusheng said that in fact, China has a unique advantage in the development of electric vehicles. China's proven reserves of lithium resources ranks second in the world, and lithium is an essential mineral resource for the development of electric vehicle industry. However, because China currently has only resource advantages and no technical advantages, the mining and purification technology of lithium mines still has a large gap with foreign countries, resulting in the majority of lithium products used in batteries being imported.

"In a sense, the future competition for electric vehicles is mainly a competition of battery performance. Whoever masters the battery's leading technology and industrializes it, who will take the initiative in the future car market." Yang Yusheng pointed out The focus of government and enterprises must focus on China's mastery of core technologies, establishment of independent intellectual property rights, and promotion of industrialization on this basis. It is absolutely not an emergency to first buy key components from foreign countries to spell out a few cars and to create a "virtual heat."

Yang Yusheng also pointed out that because the domestic car companies do not master the core technologies of the internal combustion engine cars, a large amount of profits have fallen into the hands of foreign companies that have mastered core technologies. The power battery must learn this lesson and eliminate the idea of ​​shortcuts. It is not necessary to use external parts to assemble or engage in joint ventures, insist on self-reliance, and truly master core technologies. This will be beneficial to the long-term development of the entire lithium battery industry in China.
