User-side energy storage lithium battery in Osaka Japan

Will Japan commercialize all-solid-state batteries by 2030?

In the 2024 Battery Industry Strategy, Japan set a target of commercializing all-solid-state batteries (ASSB) by around 2030. By the end of last year, the Ministry of Economy, Trade and Industry (METI) approved a total of four major R&D projects on ASSB materials and production, including that of Toyota, Idemitsu, Mitsui Kinzoku, and TK Works.

Why are lithium-ion batteries used in portable electronic devices?

Joule 5, 998-1009 (2021). Angewandte Chemie International Edition 58, 8024-8028 (2019). Energy & Environmental Science 10, 1828–1842 (2017). Nature Communications 7, 12032 (2016). Lithium-ion batteries have been widely used for portable electronic devices because of their high energy density.

What are commercialized lithium-ion batteries?

Commercialized lithium-ion batteries are constructed utilizing layered transition metal oxides as positive electrodes, graphite as negative electrodes and organic electrolyte solutions as lithium-ion conductive electrolytes. Current lithium-ion batteries already possess close values of energy density to the theoretical values.

Will Japan regain its market dominance in next-gen battery technology?

Japan, once the forerunner in lithium-ion battery development, now hopes to regain its market dominance in the field of next-gen battery tech. According to TrendForce, Japan once accounted for more than 90% of the global lithium-ion market share.

Why are large-scale battery energy storage systems important?

Large-scale battery energy storage systems including lithium-ion batteries are regarded as essential for full-scale introduction of renewable energy sources and also power backup source in case of power failures. These systems also attract much attention globally, as they may be developed for further use of frequency response and voltage support.

Which countries are developing solid state batteries?

While China, South Korea, Europe, and the US are also engaged in active development of all solid state batteries, Japan is leading the charge offering generous subsidies to technology proponents.
