Abstract

A method is disclosed for suppressing propagation of a metal in a solid state electrolyte during cycling of an electrochemical device including the solid state electrolyte and an electrode comprising the metal. One method comprises forming the solid state electrolyte such that the solid state electrolyte has a structure comprising a plurality of grains of a metal-ion conductive material and a grain boundary phase located at some or all of grain boundaries between the grains, wherein the grain boundary phase suppresses propagation of the metal in the solid state electrolyte during cycling. Another method comprises forming the solid state electrolyte such that the solid state electrolyte is a single crystal.
