Abstract
An electrochemical capacitor (battery-capacitor) which provides high power density and rapid charging and discharging times ranging from a few milliseconds to a few seconds. The capacitor device includes at least one electrochemical cell having two electrodes and an electrolyte therebetween. The electrodes and electrolyte are capable of rapid redox kinetics with the electrodes being spaced apart by no more than 0.002 inch (5.08.times.10.sup.-3 cm) to thereby provide rapid charging and discharging times.
