Role of Separators in Batteries

Lead acid battery separator materials have progressed significantly over the history of this workhorse chemistry and is a good indicator of the arrow of progress of the entire field. The first lead acid separators were natural rubbers that had moderate porosity (∼55–65 %) with more sizes on the order of 1–10 μm.
