| Abstract: | Gel poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) polymer electrolytes doped with graphene oxide (GO) (GO/PVDF-HFP) were designed and fabricated through a phrase inversion method and followed by LiPF6 solution uptake. It was demonstrated that the as-prepared GO/PVDF-HFP polymer electrolytes have uniform porous morphologies, and their crystalline state, thermal stability, interfacial resistance, and electrolyte uptake and retention capabilities can be tuned by varying the GO contents. Further, it was found that the GO can prominently enhance the ionic conductivity of the GO/PVDF-HFP polymer electrolyte. The electrochemical property measurements show that the lithium ion batteries using as-prepared GO/PVDF-HFP polymer electrolytes afford admirable charge/discharge rate and cycle stability. |
