Abstract
An alkaline cell having an anode comprising zinc, an alkaline electrolyte solution, a separator, and a cathode comprising silver copper oxide AgCuO2, or Ag2Cu2O3, desirably in admixture with MnO2. 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.
