中文摘要：
使用了一种新型的有机电解液（三乙基甲基四氟硼酸铵/（丙烯碳酸酯＋乙腈）： MeEt3NBF4/（AN＋PC））和两种传统有机电解液（四乙基四氟硼酸铵/丙烯碳酸酯（Et4NBF4/AN）和四乙基四氟硼酸/乙腈（Et4NBF4/PC））, 制作成活性炭（AC）基软包装超级电容器. 在不同电压窗口下对新型有机电解液的循环伏安和电化学阻抗谱进行了表征, 并在0-3 V的电压窗口下, 通过循环伏安、电化学阻抗谱、恒流充放电、漏电流、自放电、循环寿命和库仑效率, 对以上三种电解液进行了综合的比较. 结果表明, 新型有机电解液综合了AN和PC各自的优点, 性能优异.
英文摘要：
We fabricated activated carbon （AC）-based supercapacitors encased in flexible packaging using a novel organic electrolyte, triethylmethylammonium tetrafluoroborate/acetonitrile ＋ propylene carbonate （MeEt3NBF,/（AN ＋ PC））, and two conventional organic electrolytes, tetraethylammonium tetralluoroborate/acetonitrile （Et1 NBF4/AN） and tetraethylammonium tetrafluoroborate/propylene carbonate （Et4 NBF1/PC）. Cyclic voltammetry and electrochemical impedance spectroscopy measurements in various voltage windows were conducted. In addition, a comprehensive comparison of these three electrolytes was conducted via data obtained from cyclic voltammetry, electrochemical impedance spectroscopy, galvanostatic charge-discharge, leakage current, self-discharge, cyclic life, and coulombic efficiency within the 0-3 V voltage window. The results indicate that MeEt3NBF4/（AN＋PC） combining the advantages of AN and PC exhibits excellent performance.
