Publication number: 20190280273Abstract: 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.Type: ApplicationFiled: February 22, 2019Publication date: September 12, 2019Applicant: Hollingsworth & Vose CompanyInventors: Gubbi Krishnappa Natesh, Mahadevaswamy Kodimole Mahadevappa, Krishna Marchigowda, Harish Moddegowdru Ramaswamy, Akshay Ashirgade, Nicolas Clement, John A. Wertz, Richard O. Angus, JR., Zhiping Jiang

Publication number: 20180269452Abstract: In some embodiments, a battery separator described herein may comprise a layer having a relatively low apparent density; for example, the density that includes any unoccupied space within the outermost boundaries of the layer may be relatively low. The low apparent density may be attributed to, at least in part, the geometry of the layer. For instance, in some embodiments, the layer may include undulations and/or have at least one non-planar surface (e.g., a corrugated layer; an embossed layer). In some embodiments, a battery comprising a layer having a relatively low apparent density may have desirable properties, including relatively low electrical resistance and/or relatively high capacity. The battery separators described herein may be well suited for a variety of battery types, including lead acid batteries.Type: ApplicationFiled: May 18, 2018Publication date: September 20, 2018Applicant: Hollingsworth & Vose CompanyInventors: Gubbi Krishnappa Natesh, Krishna Marchigowda, Basavaraju Girisha, Kameswara Rao Patchigolla Venkata, Nicolas Clement, Akshay Ashirgade, Sachin Kumar, John A.
