Abstract: A battery cell includes an enclosure and a battery cell stack including C cathode electrodes each comprising a cathode active material layer arranged on a cathode current collector, S separators, and A anode electrodes each comprising an anode active material layer arranged on an anode current collector, wherein A, C, and S are integers greater than one. The anode active material layer includes an anode active material selected from a group consisting of silicon, silicon oxide, silicon alloy, and tin, a solid-state electrolyte comprising an oxysulfide, a conductive additive, and a binder. An electrolyte includes a solvate ionic liquid.
