Japan possesses the most ASSB-related patents in the world and has been steadily establishing a supply chain over recent years with the target of achieving mass production, reports TrendForce.
Japan’s Ministry of Economy, Trade and Industry (METI) announced the “Battery Supply Assurance Program” in March 2024, which would see a subsidy of $2.24 billion for the development of the domestic EV industry chain, as well as ASSB technology.
METI approved four R&D projects in 2024 at Toyota, Idemitsu, Mitsui Kinzoku, and TK Works aimed at supporting R&D on ASSB-related materials and advanced in production technology.
China, South Korea, Europe, and the US are also engaged in active development of ASSB, but Japanese manufacturers are likely to first adopt ASSB in EVs.
