摘要：

Li1.3Al0.3Ti1.7(PO4)3 powder (LATP) is synthesized by high temperature solid phase method, and then a composite polymer electrolyte membrane Poly(Vinylidene Fluoride-Hexafluoropropylene)/LATP/graphitic-C3N4 is prepared by a simple casting method. Then, the influence of porous layered g-C3N4 on the composite polymer electrolyte membrane is studied by morphology characterization and electrochemical measurement. The experimental results show that the addition of g-C3N4 improves the ionic conductivity (2.55 x 10-5 S cm-1) and lithium ion transference number (0.647) of the composite polymer electrolyte membrane (CPE), and the CPE membrane PVDF-HFP/LATP/g-C3N4 has a broad electrochemical window (up to 5.0 V) and superior electrochemical stability.
