Japanese companies and governments develop all-solid-state batteries -Lithium - Ion Battery Equipment

According to the "Nihon Keizai Shimbun" report, the Japanese government will join hands with private enterprises to promote the development of a new generation of pure electric vehicle (EV) batteries. Starting in May, Japan's Ministry of Economy, Trade and Industry will cooperate with Toyota, Asahi Kasei, Panasonic and other automotive, materials, and electronic machinery companies to promote the development of high-efficiency all-solid-state batteries. At present, Japan is losing market share to Chinese companies in the mainstream automotive battery field. Focusing on the official popularization of pure electric vehicles, Japan will accelerate the development of a new generation of batteries to achieve a counter-offensive.(Lithium - Ion Battery Equipment)

The Ministry of Economy, Trade and Industry of Japan will invest 1.6 billion yen in the "Lithium Battery Materials Evaluation and Research Center (LIBTEC)", a technology research association that includes materials manufacturers Asahi Kasei and Toray. Large car companies such as Toyota, Nissan and Honda, as well as battery manufacturers such as Panasonic and GSYUASA will also join the development of LIBTEC.

The electrolyte of the current mainstream lithium battery is liquid, while the all-solid-state battery uses a solid electrolyte. There is no need to worry about liquid leakage, safety is improved, and assembly is easy. Since the number of parts required for an all-solid-state battery is reduced, it is possible not only to cut costs, but also to increase output power.

In the field of all-solid-state batteries, Toyota's research is considered the most advanced in the world, but it has not yet been practical. Therefore, companies in various industries from automobiles, batteries to materials will build a cooperation framework and accelerate research and development. We will use solid materials, which are more difficult to use in batteries than liquids, to advance the development of improved performance and establish safety evaluation standards.

The average cruising range of cars equipped with existing lithium batteries is around 400 kilometers. LIBTEC strives to increase the cruising range to 550 kilometers by 2025 and 800 kilometers by 2030. All-solid-state batteries are expected to be adopted by many companies.

In the automotive battery industry, Japanese companies are at the forefront, accounting for 70% of the market share in 2013. However, Chinese and Korean companies are catching up fast. Chinese companies with a market share of only 3% in 2013 expanded to 26% in 2016, while Japanese companies decreased to 41%.

Affected by the global strengthening of environmental protection restrictions, pure electric vehicles will officially begin to popularize in the future. China plans to increase the popularity of new-generation cars from 650,000 in 2016 to 80 million, and Germany plans to increase from 70,000 to 6 million. Japan plans to expand the proportion of new-generation vehicles in new vehicle sales to 20-30% by 2030, and it is expected that the market size of batteries, the core component of pure electric vehicles, will also grow significantly.

The Ministry of Economy, Trade and Industry of Japan will promote the formulation of international standards in order to grasp the global dominance of vehicle batteries. Specifically, an application to the International Electrotechnical Commission (IEC) or the like is discussed.

Japan will speed up its response from both technology development and standard formulation, and improve the presence of Japanese companies in the pure electric vehicle market.
