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.

摘要： This invention is directed to a method of making lead storage battery plates including the steps of notching a lead alloy sheet or other type of thin sheet, spreading the sheet in reticulated portions, expanding the sheet into a grid, and filling pasty active material into the reticulated portions. The strip of long material is cut, respectively, into plates of a given size. The open ends of the openings on the right and left ends produced during the cutting operation are sealed with synthetic resin frame body portions to prevent the slipping out of the active material filled into the reticulated portions. Therefore, lighter and thinner plates are continuously made with better operational efficiency.

摘要： The present invention provides a process for producing a grid for use in lead acid batteries which comprises superposing a sheet or a foil of a lead alloy on a sheet bar composed of a lead-calcium alloy, said sheet or foil of lead alloy having a composition different from that of the sheet bar and having a thickness smaller than that of the sheet bar, followed by integrating the two materials by cold rolling process to form an elementary sheet and then subjecting the elementary sheet to an expanding or punching processing.The grid obtained according to this process is improved in the charging recovery characteristics after standing in a superdischarged state and in the corrosion resistance of grid at high temperatures without deteriorating the maintenance-free characteristics of the lead-calcium alloy itself.
