Enhancing ionic conductivity in Li 6+ x Ge x P 1− x S 5 Br: impact of Li + substructure on ionic transport and solid-state battery performance

Substitution of Ge( iv ) for P( v ) in Li 6 PS 5 Br presents additional Li + sites and expanding cage-like Li + substructure. As catholyte it presents enhanced transport properties in solid-state battery cathodes.
