Abstract:
1. Energy storage device comprising: a support substrate having a first surface; a plurality of collector patches disposed on the first surface of the support substrate such that portions of the first surface are contacted by the plurality collector patches and portions are uncontacted by the plurality of collector patches; an electrolyte layer disposed on the support substrate, the electrolyte layer resting on the uncontacted portions of the first surface and having gaps in electrolyte material, each gap entirely overlying at least a portion of a corresponding collector patch; and a plurality of cathode and anode electrode elements alternately disposed in the gaps of electrolyte material on corresponding collector patches wherein the gaps of electrolyte define cross sections of electrode element-filled cavities formed in the electrolyte layer, said gaps having walls extending orthogonally from the first surface of the support substrate, the walls having a cumulated surface greater than or equal to four times the first surface of the support substrate.
