All-solid-state Li-batteries using solid-state electrolytes (SSEs) offer enhanced safety over conventional Li-ion batteries with organic liquid due to the nonflammable nature of SSEs. The superior mechanical strength SSEs can also protect against Li dendrite penetration, which enables use highest specific capacity (3861 mAh/g) and lowest redox potential (-3.04 V vs standard hydrogen electrode) anode: metal. However, contact between metal presents a major challenge, where large polarization...
