Abstract

An alkaline battery cell with increased discharge capacity is provided. Both the internal volume and the electrode interfacial surface area are increased, without unnecessarily increasing the overall cell volume, by increasing the height but not the diameter of the electrodes, thereby avoiding an unnecessary increase in the total cell volume.
