Beschreibung
Zusammenfassung:	Non-woven webs that can be used as battery separators for batteries, such as lead acid batteries, are generally provided. In some embodiments, battery separators comprising a non-woven web including one or more chemical additives are provided. The chemical additives may impart beneficial properties, such as enhanced separator stability and/or battery performance. In some embodiments, the chemical additive(s) may confer resistance to oxidation, heavy metal deposition, and/or formation of short circuits during cycling of a battery including the battery separator. The respective characteristics and/or amounts of the chemical additive(s) may be selected to impart desirable properties while having relatively minimal or no adverse effects on another property of the battery separator and/or the battery.
