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.

Battery grid

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.

Method of producing battery plates

A method of making a battery includes forming a strip of interconnected grids from a grid material by feeding a continuous strip of the grid material along a linear path aligned with the longitudinal direction of the strip and punching grid material out of the strip. Each interconnected grid includes a plurality of wires, with each wire having opposed ends joined to one of a plurality of nodes to define a plurality of open spaces. The method also includes modifying at least one of the wires at a position intermediate the opposed ends of the wire such that a first transverse cross-section taken intermediate the opposed ends of the wire differs from a second transverse cross-section of the wire taken at one of the opposed ends of the wire. The method further includes applying paste to the strip and cutting the strip to form a plurality of plates.

Method of making a battery

An alloy for casting terminals for lead-acid batteries which has good corrosion resistance, produces less dross during manufacturing, has resistance to polypropylene degradation, as well as other improved features. The alloy is composed of antimony present in the range of about 2.5-4.75%; arsenic present in the range of about 0.15-0.35%; tin present in the range of about 0.23-0.6%; copper present in the range of about 0-200 ppm; sulfur present in the range of about 0-40 ppm and the balance lead. In an alternative embodiment, copper and sulfur are replaced with selenium in the range of about 40-90 ppm.

Lead alloy for lead-acid battery terminals

Modification of the shape/surface finish of battery grid wires to improve paste adhesion

A lead acid cell including a positive plate or grid has been discovered involving Pb/Ca/Sn/Ag alloy. An interaction between tin and silver which leads to optimum tin and silver levels which are substantially different than those indicated in the prior art. The described optimum tin and silver levels results in a positive alloy with superior mechanical properties and improved corrosion resistance which leads to superior battery life in present day SLI applications. In a preferred manner, the alloy includes lead, tin in the range of about 0.8% to about 1.17%, and silver in the range of grater than 0 to about 0.015%, the percentages being based upon the total weight of the lead-based alloy.
