<i>In situ</i> formation of a Li₃N-rich interface between lithium and argyrodite solid electrolyte enabled by nitrogen doping

Abstract

N-doped lithium argyrodites exhibit a remarkable critical current density of 1.52 mA cm⁻². The Li₃N-containing SEI layer between Li and N-doped electrolyte helps solid-state batteries demonstrate prominent cycling stability and rate performance.
