Battery grids, a method for making such battery grids and lead-acid batteries using such battery grids

摘要

A method of continuously making plates for a lead-acid battery, and the resulting battery, comprise providing an electrically conductive strip of a lead or lead alloy which is fed into a grid expander which converts the strip into a continuous mesh having a top and bottom bar, feeding the continuous grid mesh into a tab blanker to form the lug for each plate in the top bar and notching the top and bottom bars at spaced locations so that what becomes the corners of the top and bottom frame bars are notched, thereafter pasting the continuous grid mesh with active material paste and then dividing the continuous grid mesh into individual plates, the method disclosed providing a process capable of being reliably run at commercial rates of speed with minimal scrap rates due to separator punctures and the like, the process thus providing sufficiently wide processing latitude which, in the preferred embodiment, can even significantly minimize out-of-specification grids that would otherwise would have to be scrapped.
