Abstract

In order to develop a high-performance separator for lithium-ion battery, in this paper, GO/PVDF composite fiber membrane with different GO content was prepared by electrospinning, and the lithium-ion batteries were assembled by using it as the separator, and the performance of the battery was tested. The spinning results show that the high content of GO may affect the normal process of electrospinning, and the average diameter of fibers in GO/PVDF film increases with the increase of the quality of GO. The battery performance test results show that the performance of the battery assembled by GO/PVDF fiber membrane is better than that of PVDF fiber membrane, the addition of GO significantly improves the cycle performance of the battery, and GO/PVDF fiber membrane is more suitable for lithium-ion battery than PVDF fiber membrane..
