Abstract
The present invention relates to a photolithographic method to produce multiple, electrically insulating microprotrusions on an electrically conducting substrate to produce and maintain substantially uniform space separation between the substrates which act as electrodes in a double layer capacitor or battery configuration. Preferably, the electrically insulating microprotrusions are an organic photocurable epoxide polymer, a photocurable acrylic polymer or combinations thereof.
