  • Patent number: 7927736
    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.

  • Patent number: 6576365
    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.

  • Publication number: 20020127474
    Abstract: A membrane comprising: (a) a hydrophobic matrix polymer, and (b) a hydrophilic non-ionic polymer, wherein the hydrophobic polymer and the hydrophilic polymer are disposed so as to form a dense selectively proton-conducting membrane. The microstructure of such a membrane can be tailored to specific functionality requirements, such as proton conductivity vs. proton selectivity, and selectivity to particular species.

  • Patent number: 6225009
    Abstract: A non-liquid electrolyte containing electrochemical cell which operates efficiently at room temperature. The cell includes (a) a non-liquid electrolyte in which protons are mobile, (b) an anode active material based on an organic compound which is a source of protons during cell discharge, or an anode active material including a metal whose cation can assume at least two different non-zero oxidation numbers and (c) a solid cathode including a compound which forms an electrochemical couple with the anode. Anode and cathode 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.
