Abstract
A capacitor-assisted, solid-state lithium-ion battery is formed by replacing at least one of the electrodes of the battery with a capacitor electrode of suitable particulate composition for the replaced battery particulate anode or cathode material. The solid-state electrodes typically contain quasi-solid-state electrode material and are separated with a layer of quasi-solid-state electrolyte material. In another embodiment the capacitor anode or cathode particles may be mixed with lithium-ion battery anode or cathode particles respectively. Preferably, the battery comprises at least two positively-charged electrodes and two negatively-charged electrodes, and the location, number and compositions of the capacitor material electrode(s) may be selected to provide a desired combination of energy and power.
