Abstract: Described herein is an all-solid-state battery comprising two or more mono cells connected in series, wherein: each mono cell comprises a lithium-based cathode, a sulfide solid electrolyte, and an anode; and adjacent mono cells are connected through a single, shared current collector in contact with a cathode and an anode of adjacent mono cells. The all-solid-state battery can be fabricated by stacking freestanding layers of the lithium-based cathode, the sulfide solid electrolyte, the anode, and the current collector in a bipolar design, and pressing the layers together to form the all-solid-state battery. The lithium-ion battery -can be incorporated into portable electronics and electric vehicles.
