A method of preparing a battery paste for a lead-acid storage battery comprising: (a) mixing a water dispersion of polyfluoroethylene with lead material, (b) adding an aqueous solution of sulfuric acid to the lead material-dispersion mix and mixing to form a paste having fibrillation developed therein, (c) controlling the amount of fibrillation developed in the paste, and (d) controlling the paste density for use in a battery plate. The method provides an improved paste which permits substantial reduction in plate weights and density and loss of active material in the grid structure due to plate shedding over a conventional lead-acid paste. The saving in active material ranges from 10 to 30% over a conventional lead-acid paste without reduction in battery performance. |
