Following extensive research and development aimed at advancing electrical energy storage technologies, Glatfelter Corporation is launching its new OmniSep nonwoven battery separator.

OmniSep was developed to meet the demand for a battery separator that supports high charge and discharge rates (up to 16C pulse discharge), enhances safety, offers customisable features to suit various battery chemistries and is fully manufactured in the United States.

The OmniSep production platform allows the separator to be tailored to each specific application, offering high porosity for increased ionic conductivity and fast charging capabilities. Its pore size can be made smaller to increase shelf-life and various polymers can be used to meet the temperature and safety requirements of each application. The standard grades of 15 and 22µm are thermally stable up to 150ºC, with developmental grades stable up to 200ºC, eliminating the need for any ceramic coatings.

OmniSep’s advanced fibre design enhances hydrophilicity, promoting fast wet-out and filling, lower ionic resistance and suitability for aqueous systems. This versatility has already garnered interest from several battery manufacturers who are supplying ‘extreme’ batteries.
