"Nihon Keizai Shimbun" reported on June 21 that Japan's new energy industry technology development agency announced on June 15 that it will work with companies such as Toyota Motor Corporation and Matsushita to launch the development of a new generation of highly efficient battery 'all-solid-state' core technology. Establish technology before 2022.
In the field of lithium batteries used in pure electric vehicles (EVs), Japanese companies are overtaken by Chinese companies. They will promote Japan’s research and development efforts and strive to realize the restoration of the battery industry.
Japan’s new energy industry technology development organization had previously promoted the research and development of all-solid-state batteries with material manufacturers as the center. Toyota, Nissan Motors, and Honda and other auto makers also joined the new project that was established on June 15. The total number of cooperative companies reached 23. The research will be started with the goal of mass production and loading on pure electric vehicles.
The main components of lithium batteries use liquid electrolytes, and there are many issues in terms of cruising range and cost. Since all solid-state batteries use solid parts, there is no need to worry about leakage, the safety performance is improved, and the output power is also higher. At the same time, it is easy to implement. Miniaturization, design freedom will also increase.
This project will strive to establish the core technology of all-solid-state batteries by 2022. By 2030, the cost per kilowatt-hour battery pack will be reduced to about one-third of that of lithium-ion batteries (about 10,000 yen), and the fast charging time will also be reduced. Reduced to one-third (10 minutes).
The development of vehicle batteries requires nationwide efforts to build a development system. In China, battery manufacturers with government support have grown rapidly. According to a survey company Techno Systems Research, Matsushita, which had long occupied the top position in the global market for lithium battery cells, took hold in 2014. With a share of 44%, it is expected to decline to 16% by 2018. China's Ningde Times New Energy Technology (CATL) has taken the lead in Panasonic’s share.
Around the all-solid-state battery, Japan leads the world in the development of electrolyte materials. Hosokawa Hosokawa, project manager of Japan's New Energy Industry Technology Development Agency, also stated that 'half of all solid-state battery patents come from Japan'. Therefore, plans to use Toyota, etc. With the participation of large automakers, counterattack. The head of Panasonic's Institute of Resources and Energy Research, Fujii Imaging, stressed that 'as a battery manufacturer, it cannot be lost to overseas companies in the field of all-solid-state batteries'.
Toyota is the leader in development. Toyota strived to put all-solid-state batteries into use in the first half of the 20th century. Toyota has the world's largest number of all-solid-state battery patent applications. The number of developers is about 300, which is about 50% more than in the fall of 2017. At the press conference on June 15, Toyota's battery material technology research department director Ying Ji said that 'the development has made great progress, and hopes to be practical in any case'.
How to take the lead in Chinese companies with abundant capital and abundant talents? Drawing lessons from the oversupplied by Chinese companies in areas such as semiconductors and LCD panels, Japan’s accelerated development is crucial.
