摘要： The present invention relates to a high capacity electrochemical cell (18) including a cathode (24) that can contain an oxide of copper as an active material, an anode (26), an electrolyte, and a separator (32) 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 .025%.

摘要： 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.
