A method of forming battery grids or plates that includes the step of mechanically reshaping or refinishing battery grid wires to improve adhesion between the battery paste and the grid wires. The method is particularly useful in improving the paste adhesion to battery grids formed by a continuous battery grid making process (such as strip expansion, strip stamping, continuous casting) that produces grid wires and nodes with smooth surfaces and a rectangular cross-section. In a preferred version of the method, the grid wires of battery grids produced by a stamping process are deformed such that the grid wires have a cross-section other than the rectangular cross-section produced by the stamping process. The method increases the cycle life of a battery.

[ What is claimed is:] [1.]1. 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.
