摘要： A method of making a grid for a battery plate of a lead-acid battery. A substantially planar web is manufactured to include a plurality of spaced apart and interconnected wire segments, which at least partially define substantially planar surfaces, have a plurality of transverse lands, and interconnect at a plurality of nodes to define a plurality of open spaces between the wire segments. The web is reformed to change the cross-sectional shape of the wire segments. Other aspects may include simultaneously reducing the thickness of at least a portion of the web while reshaping the wire segments, and/or providing a controlled surface roughness on at least one of the surfaces of the web to increase surface area of the grid and thereby promote adhesion of an electrochemically active material to the grid.

摘要： 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.

摘要： A method of making a lead alloy grid for use in a plate for a lead acid battery that enables thin battery plates with a high surface area. The method of the present invention includes forming the lead alloy, such as by direct casting, to a very small thickness, then work hardening the cast strip to create a grid by forming indentations and protrusions in the thinly cast alloy strip, which in addition to strengthening the strip, provides a desirable surface topography for paste adhesion and interface characteristics. The work hardening, for example embossing, may further include splitting the strip at a high point of the protrusions and indentations to create perforated protrusions and indentations. The grid may then be used to make a plate by pasting an active mass onto the grid, steaming the pasted grid, and curing the pasted grid to provide a plate having a thickness of about 0.05 inch or less. There is further provided a lead alloy grid for use in a plate of a lead acid battery, the grid comprising a cast lead-tin-calcium alloy having spaced protrusions and indentations on each opposing surface of the grid. The protrusions and indentations may further include a perforation. The grid has a higher surface area than punched or expanded grids, thereby providing a lower resistance and better adherence at the paste/grid interface.

摘要： The present invention provides a process for producing a grid for use in lead acid batteries which comprises superposing, on a sheet bar of a lead-calcium alloy, a sheet or a foil of a lead-silver-tin alloy consisting of 0.01-1.0% by weight of tin and a residual quantity of lead and having a thickness smaller than that of the sheet bar, pressure-bonding both the materials by cold rolling to prepare an elementary sheet, and subjecting the elementary sheet to an expanding process or a punching process.The grid obtained according to the process of the invention is improved in the charge-discovery characteristics after overdischarging and standing and does not deteriorate the maintenance-free characteristic of lead-calcium-tin alloy.
