Abstract
A primary lithium cell having an anode comprising lithium and a cathode comprising electrochemically active material selected from silver copper oxides having the formula AgCuO2 or Ag2Cu2O3 or 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.
