A capacitive electrical energy storage structure is fabricated as a thin-film device comprising electrodes on opposite sides of a dielectric layer. In one approach, a high surface area metallic sponge can be incorporated into the structure. The energy storage structure can comprise either single or multiple layers of capacitors connected in series, parallel, or a combination of such arrangements. The multi-layer capacitor structure can be either applied directly to supporting structures of portable or transportable devices or can be fabricated as a film which is applied as a laminate to such structures. Further, a conformal energy storage structure can be produced which is shaped to fit in voids within devices, which voids would otherwise be little used or unused. A high capacity storage thin-film structure can be fabricated on one surface of a substrate with an immediately adjacent, overlapping power consuming electronic circuit such that power is available at very short distance to support operational circuits which cannot tolerate long conductive power supply lines. Portable consumer devices can be fabricated with the interiors of the housings conformally coated with the capacitive structure for providing energy storage as a replacement to rechargeable or disposable batteries. A flexible film of the capacitive structure can be manufactured by a continuous process and this film can be utilized in many different configurations to provide energy storage which is lightweight, configurable to available space, and capable of providing both high energy and high power density.
