    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.

    Abstract: Solid-state electrodes and methods of forming solid-state electrodes and batteries are provided. The method includes contacting an electrode precursor with a liquid. The liquid includes one or more precursors of an ionically conductive polymer. The electrode precursor includes a plurality of electroactive particles and a plurality of electrolyte particles disposed on a current collector. A plurality of interparticle pores exists between the electroactive and electrolyte particles. When the electrode precursor is contacted with the liquid, the liquid flows into the interparticle pores. The one or more precursors of the ionically conductive polymer are electropolymerized so as to cause the formation of a polymeric matrix (including the ionically conductive polymer) that surrounds and embeds the plurality of electroactive particles and the plurality of electrolyte particles so as to form the solid-state electrode.

    Abstract: Lithium-based and sodium-based batteries and capacitors using metal foil current collectors, coated with porous layers of particles of active electrode materials for producing an electric current, may adapted to produce heat for enhancing output when the cells are required to periodically operate during low ambient temperatures. A self-heating cell may be placed in heat transfer contact with a working cell that is temporarily in a cold environment. Or one or both of the anode current collector and cathode current collectors of a heating cell may be formed with shaped extended portions, uncoated with electrode materials, through which cell current may be passed for resistance heating of the extended current collector areas. These extended current collector areas may be used to heat the working area of the cell in which they are incorporated, or to contact and heat an adjacent working cell.
