An ultracapacitor having two porous organic membrane electrodes is made from microporous polymer substrates (10). The surface of the polymer substrate and the walls of the micropores (30) are coated with metal oxides. Both sides of the substrate can be coated with the conductive materials. The film can be a carboxylic ion-exchange material dispersed in a microporous copolymer matrix, and the film can be supported on a woven nylon substrate. The two electrodes (82, 84) are situated substantially parallel to each other, with the coated surface of one electrode facing the coated surface of the other electrode. An ionic electrolyte solution (89) fills the gap (86) between the electrodes.
