15 Claims

1. A battery or capacitor comprising:

a working cell comprising a working anode, a working cathode, and a first porous separator disposed therebetween, the working anode including a working anode current collector foil having a first anode material layer including particles of a first active anode material comprising graphite bonded to the working anode current collector foil, and the working cathode including a working cathode current collector foil having a first cathode material layer including particles of a first active cathode material bonded to the working cathode current collector foil; and

a self-heating cell disposed in heat transfer contact with the working cell, the self-heating cell comprising a heating anode, a heating cathode, and a second porous separator disposed therebetween, the heating anode including a heating anode current collector foil having a second anode material layer including particles of a second active anode material comprising lithium titanate bonded to the heating anode current collector foil, the heating cathode including a heating cathode current collector foil having a second cathode material layer including particles of a second active cathode material comprising lithium manganese oxide bonded to the heating cathode current collector foil, and each of the heating anode and cathode current collector foils being in electrical contact with an external electrical circuit,

wherein, when an electrical current is produced by the self-heating cell and passed through the external electrical circuit, heat is generated in the self-heating cell by electrical resistance heating and heat is transferred from the self-heating cell to the working cell.

8. A lithium-based battery, the battery comprising:

a self-heating cell disposed in heat transfer contact with the working cell, the self-heating cell comprising a heating anode, a heating cathode, and a second porous separator disposed therebetween, the heating anode including a heating anode current collector foil having a second anode material layer including particles of a second active anode material comprising lithium titanate bonded to the heating anode current collector foil, the heating cathode including a heating cathode current collector foil having a second cathode material layer including particles of a second active cathode material bonded to the heating cathode current collector foil, and each of the heating anode and cathode current collector foils being in electrical contact with an external electrical circuit; and
