Abstract : A simple method has been developed for the impregnation of activated carbon with manganese dioxide. The operational characteristics of an air cathode made from this material are superior to those previously reported for the C-MnO2 electrode. A zinc-air bicell equipped with this cathode operated with an energy density of 89 Wh/lb and maintained a cell voltage greater than 1.0 V when discharged at current densities up to 100 mA/sq cm. The C-MnO2 air cathode appears to be well suited for use in a reserve primary 'throw-away zinc-air battery. (Author)
