Abstract
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.
