Abstract

Non-woven fabrics were modified via radiation-induced grafting of styrene (St) and then immersed in the mixed solution of butanone/PVdF- HFP/butanol to prepare porous composite polymer electrolyte membranes. The obtained composite membranes supported by non-woven fabrics have appropriate thickness and good mechanical strength. Radiation grafting enhances the interaction between non-woven fabrics and PVdF-HFP-based polymer mixtures. Finally, the lithium-ion battery assembled with the obtained membrane was tested, which exhibits higher capability and better cycling performance.EI0SUPPL.44-474
