A primary lithium cell having an anode comprising lithium and a cathode comprising electrochemically active material selected from silver copper oxides having the formula AgCuOor AgCuOor mixtures thereof. The cathode can include a manganese dioxide in admixture with said silver copper oxides. The cell exhibits higher capacity and energy output than conventional lithium cells having an anode comprising lithium and cathode comprising manganese dioxide.

Lithium cell with improved cathode

An alkaline cell having an anode comprising zinc, an alkaline electrolyte solution, a separator, and a cathode comprising silver copper oxide AgCuO , or Ag Cu O , desirably in admixture with MnO . The cathode preferably also includes a graphitic carbon to improve electrical conductivity. The graphtic carbon can comprise natural or synthetic graphites including expanded graphites and graphitic carbon fibers. The carbon nanofibers desirably have a mean average diameter less than 500 nanometers.

Alkaline cell with improved cathode

An alkaline cell having an anode comprising zinc, an alkaline electrolyte solution, a separator, and a cathode comprising silver copper oxide selected from the compounds AgCuO Ag Cu O or any mixture thereof. The cathode preferably also includes a graphitic carbon to improve electrical conductivity. The graphitic carbon can comprise natural or synthetic graphites including expanded graphites and graphitic carbon fibers. The carbon nanofibers desirably have a mean average diameter less than 500 nanometers.
