A process and apparatus for continuously mixing and applying paste to battery grids for use in lead-acid battery systems, in which particulate lead oxide, water and sulphuric acid are reacted in an elongated mixer having a mixing to conveying ratio of about 65:35 to 80:20 with controlled reaction temperature for an exit product temperature in the range of above 60&#xb0; C. to about 80&#xb0; C. Additives including reinforcing fibers can be added in an amount up to 0.6 wt % of the lead oxide and carbon and graphite powder can be added in an amount up to 6 wt % of the lead oxide.

Method and apparatus for continuously mixing battery pastes

A method of producing lead alloy strip for fabrication of positive and negative electrodes of a lead-acid battery by extruding a lead alloy at elevated temperature to produce a lead alloy strip having a desired profile and rapidly cooling the extruded strip to acquire a desired microstructure. Battery grids produced from the lead alloy strip have reduced vertical growth and enhanced resistance to corrosion.
