Zusammenfassung:	Battery separators and methods of making such separators are provided. The separators can be used in various alkaline batteries such as a Zn/MnO2 battery or the like. An alkaline battery separator comprises a first layer of polyvinyl alcohol fibers, a second layer of cellulose or a cellulose derivative and a third layer comprising a water soluble polymer. The battery separator has reduced pore sizes to reduce clogging, while still maintaining desirable wet ionic resistance, basis weight and absorption performance.
