ABSTRACT:
An air assisted alkaline cell having a cathode made from a mixture of porous manganese dioxide and substantially less porous manganese dioxide. The substantially solid MnO.sub.2 is the major component of the cathode with the porous MnO.sub.2 being present in an amount effective to enable recharging of the cathode of the air assisted alkaline cell in the presence of air. The composition of the cathode is disclosed as well as the method of making the cathode. An improved air assisted alkaline cell is also disclosed, as well as the method for making the improved air assisted cell.
