原位制备P(VDF-HFP)/SiO2复合聚合物电解质及其性能研究
In-situ preparation and performance study on P(VDF-HFP)/SiO2 composite polymer electrolyte
摘要
Abstract
P (VDF-HFP)/SiO2 composite polymer electrolyte (CPE) membranes were prepared by phase inversion method,and the desirable CPEs were obtained after being activated into 1.0 mol/LiPF6-EC/DMC/EMC (1 ∶ 1 ∶ 1,v/v/v) liquid electrolytes for 30 min.The physicochemical performance of the as-prepared CPEs was characterized by SEM,XRD,LSV and EIS.The results of SEM indicate that the as-prepared P(VDF-HFP)/SiO2 membrane synthesized via in-situ polymerization presents homogeneous surface and abundant interconnected micro-pores,and the results of XRD show that there may exist interaction forces between SiO2 and polymer matrix.The results of EIS and LSV also show that the ionic conductivity and electrochemical working window of P (VDF-HFP)/SiO2 CPE membrane can reach 3.134 x 10-3 S/cm and 5.0 V,respectively.And the interfacial impedance is directfy dropped from 920 Ω to 850 Ω compared to the as-prepared composite membrane with adding SiO2.关键词
