We will deliver a summary report from the NHK article.

Practical use of all-solid-state batteries in Japan

We are accelerating the development of high-performance next-generation batteries, all-solid-state batteries.

There is a series of moves to strengthen efforts toward mass production.

▽Toyota Motor Corporation

We aim to commercialize an all-solid-state battery by 2027 at the earliest.

▽Nissan Motor

We aim to commercialize all-solid-state batteries by FY2028.

▽Honda

In the latter half of the 2020s, we aim to commercialize all-solid-state batteries.

All-solid-state battery component manufacturers:

Idemitsu Kosan:

Starting this month,

we have constructed a “solid electrolyte” demonstration plant

for “all-solid-state batteries” in Chiba Prefecture.

We aim to establish mass production technology by the end of 2027.

Lithium Battery Materials Department: Keiko Okano

The challenge is to mass-produce high-quality solid electrolytes.

We would like to establish a mass production technology by repeating demonstrations here.

Mass production of solid electrolytes:

Attention is focused on whether Japanese companies,

including material manufacturers, can lead the technology.

Mitsui Kinzoku solid electrolytes:

Increase the number of test facility lines in Saitama Prefecture.

Sumitomo Metal Mining Solid Electrolyte:

The policy is to introduce a demonstration facility for battery materials in Ehime Prefecture.
