超级电容器用季铵盐凝胶聚合物电解质的制备及性能
|
摘要
采用溶液浇注法,以聚丙烯腈(PAN)为聚合物基体,四乙基四氟硼酸铵(TEABF_4)为电解质盐,二甲基亚砜(DMSO)为增塑剂制备PAN/TEABF_4凝胶聚合物电解质。采用红外光谱(FT-IR)、热重分析(TG-DTG)以及电导率、循环伏安和恒流充放电等电化学性能测试方法,探究不同的TEABF_4与PAN质量配比对PAN/TEABF_4凝胶聚合物电解质性能的影响。当TEABF_4与PAN质量比为0.5时所制得凝胶聚合物电解质性能最佳:电导率为5.583×10~(–3)S/cm、比电容为27.59 F/g、充放电效率为86.63%、能量密度为100.58 J/g、功率密度为0.675×103 W/kg。
PAN/TEABF_4 gel ploymer electrolyte was prepared using polyacrylonitrile(PAN), tetraethyl ammonium tetrafluoroborate(TEABF_4) and dimethyl sulfoxide(DMSO) as matrix polymer, electrolyte salt and plasticizer respectively, through the solution casting technique. The effects of different mass ratios of TEABF_4 to PAN on properties of PAN/TEABF_4 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 TEABF_4 to PAN is 0.5: conductivity is 5.583×10~(–3)S/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.
