Disclosed is a solid electrolyte for a solid-state battery, preferably an all-solid-state battery, which may be protected from moisture by chemically reacting a material such as an amphiphilic compound, e.g., a surfactant with a sulfide-containing solid el...

A compound A containing Li, S, and M elements (M is phosphorus or the like), and containing a crystal phase with an argyrodite-type crystal structure is prepared, and the compound A and a conductive material are mixed to obtain a composite material in whic...

It relates to a solid electrolyte and an all-solid-state battery containing it, which contains a sulfur compound represented by Chemical Formula 1 below and B in an amount of 10 ppm to 100,000 ppm. [Chemical Formula 1] LiPSClBr (In the Chemical Formula 1, ...

The object of the present invention is to provide a battery system in which reductive decomposition of a Ge-containing solid electrolyte material is restricted. The present invention attains the object by providing a battery system comprising a battery and...
