Separator requirements. An ideal separator should have an infinite electronic but a zero ionic resistance. In practice, the electrical resistivity of the polymers used for separators is in the order of 10 12 –10 14 Ω cm, i.e., they are electrical insulators. In the meantime, a low internal ionic resistance is especially important for HEV/EV …
