Abstract
New porous separators based on non-polyolefin materials including the blend of poly (vinyl chloride)co-HFP)/poly(methyl methacrylate) (PMA), and theporous separator based on poly (vinylidene fluoride) (PVdF) were prepared by phase inversion method. The porosityand morphology were controlled with phase inversion rate, which is governed by the relative content of non-solventand solvent in coagulation bath. To enhance tensile strength, the solvent pre-evaporation and uni-axial stretching pro-cesses were applied. The ionic conductivity was increased with increasing stretching ratio, and tensile strength wasincreased with increasing solvent pre-evaporation time and 56 MPa of tensile strength, and the ionic conductivity of the stretched PVdF separator was 8.6
