Abstract: Apparatus and methodology subject matters relate to an improved electrochemical single or multi-cell energy storage device. Also, an outer casing may be provided as a pair of U-shaped shells, a single foil piece, or a tube-shaped structure which encases the internal electro chemical cell stack. The energy storage device and such casing when used advantageously exhibit low internal resistance, low ESR, a high voltage/capacity, and a low contact resistance between the internal stack and the outer casing.

Abstract: An ultra-thin electrochemical multi-cell energy storage device is provided within a single lightweight flexible casing. The energy storage device utilizes perforated isolating frames to form its internal structure. By adhering multi-layer current collectors to the perforated isolating frames, filling the openings formed therein with electrode material and stacking the current collectors with an electrolyte between the electrodes the assembly generated places the multiple cells in a plurality of stacks and all of the cells may be in series, parallel or some combination thereof by virtue of the assembly's construction. The external current collectors have good lateral conductivity due to their composite structure and provide for pressure insensitive interfacial contacts. The energy storage device advantageously exhibits low resistance, low ESR, and a high voltage/capacity while preferably remaining less than one millimeter thick.

Abstract: A non-liquid electrolyte containing electrochemical cell which operates efficiently at room temperature. The cell includes: (a) a non-liquid electrolyte (14) in which protons are mobile; (b) an anode (10) including an active material based on the organic compound which is a source of protons during cell discharge; and (c) a solid cathode (12) including a compound which forms an electrochemical couple with the anode. The active materials can be chosen so that the cell has the feature that the electrochemical reactions at the anode and cathode are at least partially reversible. An important feature of the cell is that no thermal activation is required for its operation. Therefore, the cell efficiently operates under ambient temperatures.
