Abstract:
A method of making a plurality of battery plates, the method comprising:forming a strip of interconnected battery grids from a grid material, each interconnected battery grid including a grid network bordered by at least one frame element, one of the frame elements having a current collector lug, the grid network comprising a plurality of spaced apart grid wire elements, each grid wire element having opposed ends, each opposed end being joined to one of a plurality of nodes to define a plurality of open spaces in the grid network;deforming at least a portion of the grid wire elements at a position intermediate the opposed ends of the grid wire element such that a first transverse cross-section taken at the position intermediate the opposed ends of the grid wire element differs from a second transverse cross-section taken at one of the opposed ends of the opposed ends of the grid element;applying battery paste to the strip; andcutting the strip to form a plurality of battery plates,wherein the grid network and each of the frames define opposed planar surfaces, and each first transverse cross-section does not extend above or below the planar surfaces.
