Abstract

Abstract : Young's modulus, hardness, and fracture toughness are measured by instrumented nanoindentation for an amorphous Li2 S–P2 S5 Li‐ion solid electrolyte. Although low elastic modulus suggests accommodation of significant chemomechanical strain, low fracture toughness can facilitate brittle crack formation in such materials.
