Abstract
A multi-layered solid electrolyte for Li- and Na-ion batteries has a dual conductive layer that is an ionic and electronic conductive layer, in combination with an ionic conductive and electronically insulating layer. A process is for preparation of the multi-layered solid electrolyte. A solid-state battery can be prepared with the multi-layered solid electrolyte.
