    Abstract: Method for producing an improved battery separator, specifically a microporous polytetrafluoroethylene separator, having high ionic conductivity, and having a highly uniform porous structure, by mixing an aqueous dispersion of a substance which is insoluble in water and which does not precipitate or coagulate polytetrafluoroethylene from aqueous dispersion, e.g., zinc oxide, with an aqueous dispersion of polytetrafluoroethylene, casting a film of such mixture, drying the film, sintering the dried film, forming a polytetrafluoroethylene film with particles of such substance, e.g., zinc oxide, uniformly distributed in such film, and removing the particles of such substance from the polytetrafluoroethylene film, e.g., removing zinc oxide particles from the film by leaching with aqueous alkali. The resulting flexible film or separator produced by such process.

    Abstract: Method for producing a battery electrode, particularly a zinc electrode, of improved strength and stability, and which has a porous cellular structure, by mixing an aqueous dispersion of electrode material such as zinc oxide, with an aqueous dispersion of a latex type polymer such as a fluorocarbon polymer, e.g., polytetrafluoroethylene, casting a film of such mixture, drying the film, sintering the dried film, and rolling such sintered film, to form a fibrous polymer structure binding the particles of electrode material. The resulting sintered and rolled film can be employed per se as an electrode, e.g., a zinc electrode, or such film can be ground and the ground particles then compacted to form an electrode.
