    摘要： An electrochemical cell comprising a conductive casing housing an electrode assembly provided with a stack holder surrounding the electrode assembly is described. The stack holder is of an elastic material that serves to maintain the anode and cathode in a face-to-face alignment throughout discharge. This is particularly important in later stages of cell life. As the cell discharges, anode active material is physically moved from the anode to intercalate with the cathode active material. As this mass transfer occurs, the cathode becomes physically larger and the anode smaller. This can lead to misalignment. However, the stack holder prevents such misalignment by maintaining a constrictive force on the electrode assembly throughout discharge.

    摘要： A deposition process for coating a substrate with an ultrasonically generated aerosol spray of a pseudocapacitive material or a precursor thereof contacted to a substrate heated to a temperature to instantaneously solidify the pseudocapacitive material or convert the precursor to a solidified pseudocapacitive metal compound, is described. The ultrasonic aerosol droplets are much smaller in size than those produced by conventional processes and the heated substrate minimizes the possibility of contamination, thereby providing the present coating having an increased surface area. When the coated substrate is an electrode in a capacitor, a greater surface area results in an increased electrode capacitance.

    摘要： A sealed capacitor, which may be hermetic, having a generally flat, planar geometry, is described. The capacitor includes at least one electrode provided by a metallic substrate having a capacitive material contacted thereto. The coated substrate can provide at least one of the casing side walls itself or, be connected to the side wall. A most preferred form of the capacitor has the conductive substrate provided with the capacitive material formed from an ultrasonically generated aerosol.

    摘要： An lithium-iodine electrochemical cell and method of making is described. The cell comprises a lithium anode and a cathode of a charge transfer complex which includes iodine and preferably polyvinylpyridine. The iodine-containing cathode is in operative contact with both the anode the cell casing serving as the cathode current collector. Preferably the casing is composed of stainless steel that has been thermally annealed at temperatures of 1,800°F or less. The annealed stainless steel has a grain size of about ASTM 7 or finer. When the iodine-containing cathode material in liquid form is filled into the casing, it contacts the inner casing surface. The passivation layer that subsequently forms at the contact interface affects cell impedance during discharge. It is desirable to maintain the internal impedance as low as possible.
