超级电容器用季铵盐凝胶聚合物电解质的制备及性能
Preparation and performance of quaternary ammonium salt gel polymer electrolyte for supercapacitor
摘要
Abstract
PAN/TEABF4 gel ploymer electrolyte was prepared using polyacrylonitrile (PAN),tetraethyl ammonium tetrafluoroborate (TEABF4) and dimethyl sulfoxide (DMSO) as matrix polymer,electrolyte salt and plasticizer respectively,through the solution casting technique.The effects of different mass ratios of TEABF4 to PAN on properties of PAN/TEABF4 gel polymer electrolyte were investigated by FT-IR,TG-DTG,and conductivity,cyclic voltammetry,constant current charge/discharge and other electrochemical performance.The results show that gel polymer electrolyte displays the best performance when the mass ratio of TEABF4 to PAN is 0.5:conductivity is 5.583×10-3S /cm,the specific capacitance is about 27.59 F/g,the charge/discharge efficiency is 86.63％,the energy density is 100.58 J/g,and the power density is 0.675× 103 W/kg.关键词
