TOKYO -- A Japanese company has developed a new material with a government lab that it says will greatly extend the life of solid-state batteries, an emerging next-generation technology.

Koike, a subsidiary of finance company Orix, worked with the National Institute of Advanced Industrial Science and Technology (AIST) to produce a single-crystal material that can be used as an electrolyte in solid-state batteries.
