Abstract: A battery grid is disclosed. The battery grid includes a pattern of grid wires. The pattern includes a grid wire having a first segment with a first corrosion resistance and a second segment with a second corrosion resistance which is less than the first corrosion resistance. The second segment corrodes at a rate which is faster than the corrosion rate of the first segment so as to dynamically release internal stress and control grid growth of the battery grid during its service life. A battery includes said grid and a method of forming said grid are also disclosed.

Abstract: A grid network for a battery plate is provided. The grid network includes a plurality of spaced apart grid wire elements, each grid wire element having opposed ends joined to one of a plurality of nodes. Each node includes the juncture of one of the opposed ends of a plurality of the grid wire elements to define a plurality of open spaces in the grid network. At least one of the grid wire elements has a first transverse cross-section intermediate its opposed ends that is a different shape than a second transverse cross-section at at least one of the grid wire element's opposed ends.

Abstract: A battery grid is provided having a frame having a top element, a bottom element, a first side element, and a second side element. A current collection lug is coupled to the top element. The battery grid includes a plurality of wires provided within the frame and defining a plurality of open areas. The plurality of wires includes a vertical grid wire continuously extending from the bottom element toward the top element, and a plurality of horizontal grid wires continuously extending from the first side element or second side element, wherein the vertical grid wire intersects the plurality of horizontal grid wires, but does not intersect the first side element, second side element; or top element.

Abstract: 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 past adhesion to battery grids formed by a continuous batter grid making process (such as strip expansion, strip stamping, continuous casting) that produces grid wires and nodes with smooth surfaces and 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.
