In race for better batteries, Japan hopes to extend its lead

As their name implies, solid-state batteries use solid rather than liquid materials as an electrolyte.

Because they do not leak or give off flammable vapor, as lithium-ion batteries are prone to, solid-state batteries are safer.

Solid-state batteries are a promising power source for the internet-of-things devices that are coming into wider use, and for electric cars because of their potential to offer greater range than the stacks of lithium-ion cells that power such vehicles now.

The project aims to develop technology to make solid-state automotive batteries practical and mass-produce them.

It hopes to come up with designs and develop manufacturing processes and testing methods for automotive solid-state batteries by the end of March 2023.

It is working with Japan’s Honda Motor to develop batteries for electric vehicles aimed at the Chinese market, and is set to start supplying batteries to Germany’s Volkswagen.

Japan still has the edge in solid-state batteries, with its companies holding nearly half the patents in the world for related technologies.
