Abstract
A process for making a battery paste includes steps of forming an active material in an aqueous slurry, then dewatering the slurry to form a battery paste. In one described embodiment, a slurry containing one or more basic lead sulfates suitable for use as the active material in lead-acid battery electrodes is formed in a continuously stirred tank reactor (36). The slurry is withdrawn from the reactor (36) and fed to a belt press (67) which reduces the moisture content of the slurry to the desired level. Battery pastes produced according to the invention may be fed continuously to a paster (89) for mass production of positive and negative battery plates from grids (91).
