Abstract:
Lithium-utilizing electrochemical cells, providing hybrid battery and capacitor activity, are formed of one or more lithium battery anodes, optionally also including a capacitor electrode, and one or more lithium battery cathodes, optionally with a capacitor electrode, provided that there is at least one capacitor electrode in the hybrid cell and that there are an equal number of electrodes of opposing charge. The respective electrodes are formed of porous layers of one of lithium anode material particles, lithium cathode material particles, or compatible capacitor material particles, formed on one or both sides of a compatible current collector foil. The amounts of active battery and capacitor particles are managed by the thickness of the porous coating layers, and one-side or two-side electrode coatings, to balance the capacities of the battery and capacitor particles to accept and release lithium ions during repeated charging and discharging of the hybrid cell.
