摘要：An oxidation resistant, microporous polyolefin web exhibiting high-strengthmechanical and low electrical resistance properties is a solid matrix that includes an
ultrahigh molecular weight polyolefin component and a friable precipitated silicacomponent. The ultrahigh molecular weight polyolefin component provides high-strength mechanical properties to the web. The friable precipitated silica component isbroken down into predominately discrete silica aggregates dispersed throughout themicroporous web to maintain a low electrical resistance in the presence of an electrolyte.In an alternative preferred embodiment, a polyethylene web includes an antioxidantcoating that is applied to the separator web following extraction of the majority of theprocess oils and drying of the extraction fluid from the separator pores. The resultant“sheath” of antioxidant protects the mechanical integrity of the polyethyleneseparator by suppressing polyethylene degradation.
