  • Alkaline cells having high capacity
    Patent number: 7763384
    Abstract: The present invention relates to a high capacity electrochemical cell including an anode, a cathode, and a separator disposed between the anode and cathode. The anode is configured to operate in combination with a quantity of an oxide of copper in the cathode. The cell is capable of operating at a discharge voltage greater than 1.05 volts for at least an initial 5% of a cell discharge period at a current density of at least 5 mA/g, and can include a cathode active material that includes an oxide of copper.

  • High Capacity Alkaline Cell Utilizing Cathode Extender
    Publication number: 20080038634
    Abstract: An electrochemical cell is provided that includes a container, a cathode and anode disposed in the container, and a separator disposed between the anode and cathode. The cell further includes an extender either included in or separate from the cathode. An agent is further provided that interacts with soluble ionic species generated in the cathode to prevent the migration of the species to the anode.

  • High capacity alkaline cells
    Publication number: 20050084755
    Abstract: The present invention relates to a high capacity electrochemical cell including a cathode that can contain an oxide of copper as an active material, an anode, an electrolyte, and a separator disposed between the anode and the cathode. The oxide can have surface area greater than 0.5 m2/g, and the cathode can include an additive that increases the discharge voltage of the cell. In some cases the additive has a lower voltage than the oxide alone. The additive can have a surface area within the range defined by a lower limit of 0.5 m2/g and an upper limit of 100 m2/g. The anode can include a quantity of mercury below 0.025%.
