Abstract:Compared with commercial polyolefin membranes, electrospun polymeric membranes have the advantages of higher porosity and better electrolyte wettability, but their poor mechanical performance limits their industrial use as battery separators. In this work, a layer‐to‐layer electrospinning is used for fabrication of PVdF@PMMA membranes, in which fibers in adjacent layers are arranged at a certain angle (0°, 30°, 60°, 90°). The as‐electrospun membranes are further hot‐pressed to boost their mechanical strength. … Show more
