<p>An alkaline cell (10) is disclosed having a cathode (12) comprising manganese dioxide wherein the cathode (12) is a semisolid during discharge of the cell. The cell (10) may have an anode (50) comprising zinc and an electrolyte comprising potassium hydroxide. The semisolid cathode (12) comprising manganese dioxide may be in the form of a putty or paste. The semisolid cathode (12) reduces cathode polarization effects and results in increased manganese dioxide utilization (Amp-hr/g), particularly at high current drain, between about 0.5 and 2 Amp.</p> |
