In order to promote the development of new-generation batteries, Japan uses subsidies to support domestic companies in research and development

According to the 'Yomiuri Shimbun' website, the Ministry of Economy, Trade and Industry of Japan has established a strategic policy to promote the development of high-performance batteries, the most important component of electric vehicles, in order to promote the popularization of electric vehicles that can achieve zero carbon dioxide emissions. Japan will provide support in the form of subsidies for the research and development of next-generation batteries and the preparation of production sites in Japan. This is also to establish a corresponding system to compete with overseas companies that have attracted much attention in battery development. In order to achieve the Japanese government's goal of substantially zeroing CO2 and other greenhouse gas emissions by 2050, the Ministry of Economy, Trade and Industry will include this strategic measure in the implementation plan formulated at the end of this year. It is reported that batteries account for 30% of the production cost of electric vehicles and are the most important part that affects vehicle performance. In order to improve the international competitiveness of the Japanese automobile industry, relevant policies will be formulated as a key issue. If the related technology can be further developed to achieve large capacity, it is hoped that it can lead to the development of batteries for renewable energy such as solar and wind with unstable power. In this Japanese national strategy, four measures are included to promote technology development, improve competitiveness, develop international cooperation, and promote popularization policies for 4-point vehicle batteries. In order to make the endurance of electric vehicles exceed ordinary fuel vehicles, it will promote the practical application of a new generation of 'all-solid-state batteries' as a substitute for lithium-ion batteries, and subsidies will be used to promote the technological development of emerging companies.
