Aluminum with appropriate potential, high-capacity, and electronic conductivity can alloy with Li spontaneously and is proposed herein as a carbon-free and binder-free anode of an all-solid-state Li-S battery (LSB). A biphasic lithiation reaction of Al with modest volume change was revealed by in situ characterization. The Li_0.8Al alloy anode showed excellent compatibility toward the Li₁₀GeP₂S₁₂ (LGPS) electrolyte, as verified by the steady Li_0.8Al-LGPS-Li_0.8Al cell operation for over 2500 hours at 0.5 mA cm^-2.
