Relationship between morphology and conductivity of block-copolymer based bat…

Abstract. Nanoporous battery separators were made by blending a polystyrene-block-polyethylene-blockpolystyrene copolymer (SES) and polystyrene (PS) homopolymers, casting films of the blend, and selectively dissolving the homopolymer. The efficacy of the separators thus obtained was determined by measurement of the ionic conductivity of separators soaked in 1 M lithium hexafluorophosphate i…
