ABSTRACT:
The present invention relates to a copper-manganese mixed oxide cathode material, which is suitable for use in a cathode of an electrochemical cell, and which has the formula MnxCuyOz.nH2O, wherein the oxidation state of Cu is between about +1 and about +3, the oxidation state of Mn is between about +2 and about +7, x is equal to about 3-y, y is less than about 3, z is calculated or experimentally determined, using means known in the art, based on the values of x and y, as well as the oxidation states of Mn and Cu, and nH2O represents the surface and structural water present in the mixed oxide material. The present invention further relates to an electrochemical cell comprising the noted cathode material.
