Patent ID: 8142522

Claim:
A method of making a capacitive device, the method comprising: providing planar electrodes arranged in series; applying a first electrically conductive carbon material to one or more of the electrodes such that the first electrically conductive carbon material provides electrical contact between at least two alternating electrodes; and applying an electrically insulating material between adjacent electrodes in the series; wherein the applying the first electrically conductive carbon material comprises bonding one or more sheets of the electrically conductive carbon material to each electrode; subsequently bonding one or more sheets of the electrically conductive carbon material to the one or more sheets bonded to each electrode to form a stack of bonded discrete sheets; and wherein the applying an electrically insulating material between adjacent electrodes in the series comprises forming the electrically insulating material by a method selected from lithography, photolithography, molding, printing, and combinations thereof.
