: Young’s modulus, hardness, and fracture toughness are measured by instrumented nanoindentation for amorphous Li 2 S – P 2 S 5 Li-ion solid electrolyte. Although low modulus suggests good ability to accommodate chemomechanical strain, highly brittle behavior can lead to disruptive crack formation.
