Abstract: Briefly, according to the invention, there is provided an energy storage device (5) with three electrodes. A first electrolyte (15) is situated between the first (10) and second (20) electrodes so that it is in contact with each of the electrodes, forming a battery cell (80). A second electrolyte (25) is placed between the second (20) and third (30) electrodes so that it is also in contact with each electrode, forming an electrochemical capacitor (70). The battery and capacitor each share a common electrode (20). After charging, the energy storage device can be linked to an electrical device to power it by discharging the battery portion to provide a substantially constant voltage, and discharging the capacitor portion to provide a substantially constant current when the device requires higher levels of current than the battery portion is capable of providing.
