Synthesis of porous polyvinylidene fluoride (PVDF) microspheres and their application in lithium sulfur batteries
journal contribution
posted on 2017-02-01, 00:00 authored by Tao Tao, Y Deng, Z Liang, B Liang, Y Yao, P Li, S Lu, Ying (Ian) ChenYing (Ian) ChenNovel porous PVDF microspheres have been prepared by a facile electrospraying approach. The microspheres with an average size of 2–5 µm in diameter possess inter-connective pores. Several key factors including polymer diffusion, solvent evaporation, chain entanglements and Coulomb fission influence the morphology of final products obtained by electrospraying. About 66 wt% sulfur content could be loaded into the void space of the porous PVDF microspheres. The special structure of porous PVDF microsphere serving as a host for the lithium sulfur batteries could benefit from the physical entrapment of the polysulfides.
