Abstract
An EDLC device in which the double layer capacitors themselves are produced lithographically. The resultant EDLC can be of any capacitance and voltage combination for a particular application. The entire lithographically formed entity can be housed in a single container and rated according to its capacitance and voltage standoff characteristics. Through material control processes, the electrochemical composites developed onto the current collector is unilaterally equalized, providing the desired distributed voltage standoffs, thus promoting the ability to design high voltage independent cells without the normal electronic balancing circuitry associated with multiple series-connected electrochemical cells.
