End-users and battery producers are developing and implementing more rigorous performance standards to improve battery life. Industrial batteries often experience deep cycling, partial state-of charge (PSOC) duty, and overcharge situations. The separator must participate actively in such operational environments. Flooded and gel batteries that encounter cycling conditions in motive and reserve power, electric-rickshaws and automotive applications will require a new-generation separator to reduce PSOC-hydration shorts, limit water loss, prevent oxidation, and improve electrolyte diffusion. The Hi-SepTM product ― designed by Hollingsworth & Vose (H&V) with novel fibres, fillers and binders ― has repeatedly demonstrated oxidation resistance, high electrolyte diffusion, and leachate-free characteristics. In further work, H&V has developed Hi-Sep UltimaTM, which in addition to possessing all of the performance attributes of Hi-SepTM, also reduces water loss (confirmed by antimony-suppression tests) and hydration shorts (confirmed by scanning electron micrographs and gravimetric measurements). Hi-SepTM technology delivers premium separators to maximize battery performance.
