Grid for use in lead acid batteries and process for producing same |
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.
