Abstract:
The present disclosure provides a solid-state bipolar battery that includes negative and positive electrodes having thicknesses between about 100 μm and about 3000 μm, and a solid-state electrolyte layer disposed between the negative electrode and the positive electrode and having a thickness between about 5 μm and about 100 μm. The first electrode includes a plurality of negative solid-state electroactive particles embedded on or disposed within a first porous material. The second electrode includes plurality of positive solid-state electroactive particles embedded on or disposed within a second porous material that is the same or different from the first porous material. The solid-state bipolar battery includes a first current collector foil disposed on the first porous material, and a second current collector foil disposed on the second porous material. The first and second current collector foils may each have a thickness less than or equal to about 10 μm.
