ALKALINE CELL WITH IMPROVED CATHODE

摘要

An alkaline cell (10) is disclosed having a cathode (12) comprising manganes e 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.
