Abstract
A dip method of enveloping a battery plate with a microporous battery separator material. The method involves a first removing air bubbles from the plate by dipping the plate in a liquid, then dipping the plate into a polymer-solvent-filler suspension. After removal from the polymer-solvent-filler suspension, the plate is dried by evaporation or contacted with a nonsolvent and then dried. The result is the formation of a microporous separator envelope about the battery plate.
