Hitachi Zosen has announced that it has developed one of the world's largest all-solid-state batteries amid growing demand for batteries for electric vehicles and solar power generation.

All-solid-state batteries have a solid "electrolyte" for storage and discharge, and because they can store more electricity faster in smaller sizes, they are a next-generation alternative to "lithium-ion batteries" made from liquids.

Regarding this all-solid-state battery, Hitachi Zosen announced that it has successfully developed a battery with a capacity of approximately seven times that of a conventional battery, one of the largest in the world.

It can be used in a variety of environments from -40 to 100°C. The goal is to use it in industrial machines and in space in the future.

Competition for the development of all-solid-state batteries continues globally, with Toyota Motor Corporation and Murata Manufacturing working on practical applications in Japan.
