Abstract

A battery cell, and methods of manufacturing the same, having significantly improved capacity utilization at high discharge rates while maintaining much of the energy content and other feature advantages of typical cylindrical or prismatic alkaline cells, by implementing a novel cell construction that produces increased surface area between the anode and cathode. The cell comprises an inner electrode encapsulated by a separator and disposed within the interior space of the housing. The inner electrode comprises a substantially flat material in a folded configuration and formed such that an outer extent of the inner electrode is generally conforming to a contour defined by the interior surface of the cell housing. Two outer electrode portions are disposed within the interior space of the housing such that it is in ionic communication with the inner electrode and in electrical communication with the first terminal of the cell housing.
