Abstract
An electrode for an energy storage device is made from an activated carbon support. The activated carbon has adsorbed onto it a protonated polymer, which has a polyoxometalate absorbed into the polymer. Preferably, the protonated polymer is poly(4-vinylpyridine), and the polyoxometalate is isopolymolybdate. An energy storage device, such as a capacitor, can be made from the modified carbon electrode. A pair of the coated carbon electrodes (13) are placed in contact with an electrolyte to form the device.
