  • Nickel metal hydride cells designed for high rate/low temperature performance
    Patent number: 6287724
    Abstract: A metal hydride rechargeable cell is provided that discharges during a test discharge at a rate of 8 C to 18 C and a cell temperature of 0° C. where the voltage remains above 0.2 volts during the half of the discharge curve. The cell comprises a negative electrode of hydrogen storage alloy material having a particle size volume distribution whose d(50) value does not exceed 2(2Dht)½, where Dh is the hydrogen diffusion coefficient for the alloy at 0° C. and t is a time period from about 200 to about 450 seconds. A method of manufacturing the cell of the present invention involves an activation protocol comprising at least one formation cycle, a heat treating step, and a cycling step. This method avoids unnecessary processing of the metal alloy material prior to incorporation into the negative electrode.
    Type: Grant

  • Electrode structure for nickel metal hydride cells
    Patent number: 5478594
    Abstract: An electrode is disclosed for use in a wound nickel metal hydride electrochemical cell. The electrode has an electrochemically active material carried on the substrate. The electrode includes the improvement of an effective amount of an elastic binder coating the outer surface of the active material to enhance the integrity of the electrode and to substantially inhibit infantile shorting during operation thereof.
