Abstract
An electrochemical capacitor device (10) including an anode (20) and a cathode (30) separated by a separator (40) and surrounded by an electrolyte (50). The anode (20) and cathode (30) is fabricated from a multi-valent, multiple oxidation state material. The material has a high, an intermediate, and a low oxidation state. In an initial condition, both the anode and cathode are in the intermediate oxidation state. During charging, one electrode will be oxidized to the higher states, while the other electrode will be reduced to the lower state. The processes are reversed during discharge.
