20080289161 | NETHOD FOR MAKING BATTERY PLATES - A method of making a plurality of battery plates includes forming a strip including a plurality of battery grids. Each battery grid includes a grid network bordered by a frame element and includes a plurality of spaced apart grid wire elements. Each grid wire element has opposed ends joined to one of a plurality of nodes to define a plurality of open spaces in the grid network. The method also includes deforming at least a portion of a plurality of the grid wire elements such that the deformed grid wire elements have a first transverse cross-section at a point intermediate their opposed ends that differs from a second transverse cross-section taken at least one of their opposed ends. The method also includes applying a lead alloy coating to the strip, applying battery paste to the strip, and cutting the strip to form a plurality of battery plates. | 11-27-2008 |
20090000089 | Apparatus for producing a grid for a battery plate, and method of producing the same - A method where two disk cutter rolls are used to form slits in a staggered pattern in a metal sheet; disk cutters are part of the disk cutter rolls; ridges are arranged in a peripheral edge of the disk cutters; and valleys are arranged between the ridges, where an axis-to-axis distance L (mm) of the rolls satisfies a relationship of 2r−0.3≦L<2r when a radius of a reference circumferential face made with the valleys is r (mm). The method can include a carrying procedure for passing the sheet between the rolls, then carrying the sheet along a peripheral face of one of the rolls, and then pulling out the sheet from the peripheral face. | 01-01-2009 |

20090172932 | Method of manufacturing a lead or a lead alloy plate lattice for a lead-acid battery - A method of manufacturing a lead or a lead alloy plate lattice for a lead-acid battery, featured in that a melt of lead or a lead alloy is continuously extruded under temperatures lower by 10 to 100° C. than the melting point of the lead or the lead alloy, followed by subjecting the extrudate to cold rolling under temperatures lower by 50 to 230° C. than the melting point of the lead or the lead alloy with the total draft rate set at 10 to 90% and subsequently cooling and processing the cold rolled extrudate so as to manufacture a plate lattice. | 07-09-2009 |
20100011550 | Controlled corrosion processes utilizing one atmosphere glow discharge plasma (OAGDP) in the manufacture of lead acid batteries - Controlled corrosion processes in the production of lead acid batteries, wherein the processes utilize one atmospheric glow discharge plasma (OAGDP) to generate etched and chemically altered grids to increase the development of electrically conductive lead dioxide. The process involves placing pasted or unpasted lead or lead alloy grids in a chamber having two plasma-generating electrodes therein. A feed stream is directed into the chamber and passes between the electrodes to develop a plasma at atmospheric pressure. In the plasma, the components of the feed stream break down into atomic and reactive species to create a reactive environment. When the lead or lead alloy grids are exposed the reactive environment, chemical reactions occur between the reactive species and the lead components in the grids to chemically etch and remove contaminates from the grids, as well as form a uniform crystalline structure of lead nitrate across the grid surface, which can react to form a layer of lead dioxide on the grid surface. | 01-21-2010 |
20100319172 | Method of Making a Current Collector - A method of manufacturing a current collector comprising embossing a sheet comprising lead thereby forming an embossed grid comprising rows of raised portions and lowered portions, and slots comprising edges of the raised portions and lowered portions; creating areas for tab creation by pressing or stamping areas of the embossed grid to a flattened state, thereby forming a sheet comprising embossed grid sections and flat sections; applying paste to the top and bottom of the embossed grid sections; and stamping current collectors out of the sheet such that at least one tab is created from a flat section. | 12-23-2010 |

20120096695 | METHOD OF MAKING A BATTERY PLATE - A battery grid includes a grid network having a plurality of spaced apart grid wire elements. Each grid wire element has opposed ends joined to one of a plurality of nodes, each node includes a juncture of one of one of the opposed ends of the plurality of grid wire elements, to define a plurality of open spaces in the grid network. In various embodiments, 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. In various embodiments, the battery grid also includes a lead alloy coating on substantially all of the grid wire elements, wherein the lead alloy coating is exposed to an inert gas during the coating of the grid wire elements. | 04-26-2012 |
20150040361 | MACHINE FOR DEFORMING THE WIRES OF GRIDS FOR MAKING ELECTRIC ACCUMULATORS - A machine for deforming the wires of grids for making electric accumulators, which comprises two lower moulds, and two upper moulds which are positioned above the lower moulds and which are operable to shift between a raised position, in which they are separated from the underlying lower moulds, and a lowered position in which they are pressed against the lower moulds to deform the wires of the grids on a grid strip. The upper moulds comprise respective projecting moulding areas and respective seats which are positioned between the moulding areas of the relative upper mould, and each housing a corresponding piece-detacher element which, when the upper moulds are in the raised position, is suitable to interfere with the grid remaining attached to the corresponding upper mould to separate the grid from such upper mould. | 02-12-2015 |
