Thin lithium battery with slurry cathode

An IC card comprising an electronic device and a battery within a plastic card for electrically energizing the electronic device. The battery is comprised of a monolithic electrochemical cell having a lithium-containing cathode, a carbon anode, and a porous polymer separator infused with electrolyte solution. The cell has a thickness of less than 0.7 mm. A package containing the cell formed of a sheet of flexible laminate material having at least one metal foil layer and a layer of an adhesive-like polymeric material. The battery has an overall thickness of less than 0.8 mm.

IC card with thin battery

The present invention provides a limited rechargeable lithium battery containing an anode; a cathode slurry containing about 55 to about 75% by weight of a transition metal oxide, about 3 to about 8% by weight of a conductor, and about 20 to about 40% by weight of an organic electrolyte containing an electrolyte salt and an organic solvent; a separator between the anode and the cathode slurry; and at least two current collectors. The present invention also provides a method of making a cathode slurry.
