Abstract
There is disclosed a flexible separator for use between the electrodes of Ni-Cd and Ni-Zn batteries using alkaline electrolytes. The separator is made by coating a porous substrate such as sheets or mats of asbestos or other materials with a battery separator composition. The coating material includes a rubber-based resin copolymer, a plasticizer and inorganic and organic fillers which comprise 55% by volume or less of the coating as finally dried. One or more of the filler materials, whether organic or inorganic, is preferably active with the alkaline electrolyte to produce pores in the separator coating. The plasticizer is an organic additive such as a material which is hydrolyzed by the alkaline electrolyte to improve conductivity of the separator coating.
