An improved dip method of enveloping a battery plate with a microporous separator material. The method involves first removing air bubbles and residual water from the plate by dipping the plate in an anhydrous liquid such as anhydrous solvent or anhydrous solvent/nonsolvent solution, then dipping the plate in a second liquid comprising a polymer-solvent-filler or polymer-solvent/nonsolvent-filler suspension. After removal from the second liquid, the plate is dried by evaporation. The result is the formation of a microporous separator envelope about the battery plate. The plate may be dipped in a third liquid before drying. The third liquid may have a viscosity greater than that of the second liquid.
