Abstract:
A battery plate comprising:a lead grid embedded in a dried body of a battery paste; and a pasting paper sheet, wherein before being dried, the battery paste consists essentially of at least one lead oxide, at least one lead sulfate, sufficient water to moisten the paste, sufficient sulfuric acid to moisten the paste and form the desired lead sulfate, and from 1 percent to 6 percent, based on the weight of the lead oxide plus the weight of the lead sulfate, calculated as the lead oxide, of glass fibers having an average diameter of from 0.25 micron to 10 microns and having their glass surfaces in direct contact with the lead oxide, before being dried, the battery paste is prepared by a method that comprises charging the water, the lead oxide or oxides, in the proportions desired in the paste, and the glass fibers to a mechanical mixer, subjecting the water, lead oxide or oxides and glass fibers to mixing, adding the sulfuric acid required to form the lead sulfate, and completing the mixing of the paste, and the battery plate has substantially parallel major surfaces and a plurality of minor surfaces extending between said major surfaces, and the pasting paper sheet is on at least one of said major surfaces.
