Abstract
A continuous paste making process for lead acid batteries that includes the steps of mixing water with a lead oxide, reaction an acid with the lead oxide in a mixture to produce lead acid compounds, and forming a paste including interlocking lead acid crystals from the lead acid compounds, where the mixing, reacting, and crystal forming steps occur in an extrusion apparatus. The method also includes the step of extruding the paste from the extrusion apparatus into a grid where the paste is dried to form a battery plate of the lead-acid battery.
