Abstract
Lithium-utilizing electrochemical cells, providing battery and hybrid-capacitor activity, are formed of one or more lithium battery anodes, one or more lithium battery cathodes, and one or more positive-charge or negative-charge hybrid capacitor electrodes which are formed of a combination of capacitor particles with one of anode or cathode particles. The anode and cathodes are formed of porous layers of particles of anode or cathode material, bonded to each side of a current collector foil. The hybrid capacitor electrodes are formed of porous layers of capacitor particles, mixed or layered with anode or capacitor particles, bonded to each side of a current collector foil. The compositions of the hybrid capacitors are determined to balance the capacities of the electrodes in the lithium-ion electrochemical cell to intercalate or adsorb lithium cations and corresponding anions in the electrolyte infiltrating the pores of the electrode materials.
