Abstract
A battery electrode design and a flat stack battery cell design preferably include structure and/or manufacturing steps whereby a battery electrode plate has a frame, and a grid-array of elements disposed interiorly of the frame. A first collector pole access channel is disposed interiorly of the frame and orthogonal with respect to the grid-array of elements, and a second collector pole access channel is also disposed interiorly of the frame and orthogonal with respect to the grid-array of elements. Preferably, the collector pole access channels are made by hole-punching lead slugs integrally disposed in the grid-array. Preferably, the electrode plates are a standard size, and may be disposed in a common jar; thus, the battery capacity is determined by the number of electrode plates in the jar, the jar being trimmed per the number of electrode plates.
