CLAD CURRENT COLLECTORS INCLUDING THERMAL INTERFACE LAYER FOR BIPOLAR SOLID-STATE BATTERIES

A battery cell includes a plurality of cathodes and a plurality of anodes. A plurality of solid electrolyte layers are arranged between first adjacent ones of the plurality of cathodes and the plurality of anodes. A plurality of clad current collectors are arranged between second adjacent ones of the plurality of cathodes and the plurality of anodes. The plurality of clad current collector includes a first foil layer, a second foil layer and a thermal interface layer including adhesive and at least one material that increases thermal and electrical conductivity of the thermal interface layer.
