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 be 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. One or both of the anode current collector and cathode current collector 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.

Electrodes are formed with a porous layer of particulate electrode material bonded to each of the two major sides of a compatible metal current collector. In one embodiment, opposing electrodes are formed with like lithium-ion battery anode materials or like cathode materials or capacitor materials on both sides of the current collector. In another embodiment, a battery electrode material is applied to one side of a current collector and capacitor material is applied to the other side. In general, the electrodes are formed by combining a suitable grouping of capacitor layers with un-equal numbers of anode and cathode battery layers. One or more pairs of opposing electrodes are assembled to provide a combination of battery and capacitor energy and power properties in a hybrid electrochemical cell. The cells may be formed by stacking or winding rolls of the opposing electrodes with interposed separators.

A copper foil, intended for use as a current collector in a lithium-containing electrode for a lithium-based electrochemical cell, is subjected to a series of chemical oxidation and reduction processing steps to form a field of integral copper wires extending outwardly from the surfaces of the current collector (and from the copper content of the foil) to be coated with a resin-bonded porous layer of particles of active electrode material. The copper wires serve to anchor thicker layers of porous electrode material and enhance liquid electrolyte contact with the electrode particles and the current collector to improve the energy output of the cell and its useful life.
