Japanese solid-state energy storage

Why is Japan a leader in solid-state battery development?

This reflects Japan’s continued commitment to taking a technological leadership role in deepening global collaboration in this field.” “Japan has a rich history of battery innovation and QuantumScape is leading efforts to develop and commercialize solid-state batteries,” said Dr. Siva Sivaram.

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.

How much does it cost to build a battery factory in Japan?

Japan’s Ministry of Economy, Trade, and Industry (METI) has already approved the planned construction site. It will cost around 21.3 billion yen ($142 million) and was deemed as a “plan for ensuring supply of storage batteries.” Idemitsu aims to mass produce all-solid state batteries in 2027 and 2028.

What is Japan's goal regarding battery supply?

Japan aims to secure a stable supply of batteries as it shifts away from dependence on China or South Korea, which dominate the market. Toyota getting the green light on EV battery production could be a big step towards achieving this goal.

Will Toyota's new battery technology improve Japan's storage battery industry?

This will contribute to the government’s policy of strengthening the storage battery supply chain and improving the competitiveness of Japan’s storage battery industry, according to a press release. Toyota has been touting the new battery tech for years, but it seems to have made some progress recently, reported Electrek.

What is the capacity of a solid state battery?

The Japanese -uilt, solid-state battery has a capacity of 1,000 milliamp-hours (mAh). Additionally, it can operate within a temperature range of -40º to 100ºC (-40º to 212ºF). Solid-state batteries continue to garner research and technological advancement due to their potential for increased efficiency.
