摘要
两步法合成了N,N-二甲基吡咯烷鎓双(三氟甲基磺酰)亚胺(DMPTFSI)、N,N-二甲基吡咯烷鎓四氟硼酸盐(DMPBF4)二种离子盐,研究了这两种离子盐在乙腈中电导率性能。对所制备出超级电容器进行3. 0V,100C,15 000周循环充放电性能研究,发现N,N-二甲基吡咯烷鎓四氟硼酸盐(DMPBF4)体系电解液在电容及内阻方面表现突出。
Two kinds of ionic salts,N,N-dimethylpyrrolidinium bistriflimide(DMPTFSI),N,N-dimethylpyrrolidinium tetrafluoroborate(DMPBF4)were synthesized by two-step method.The conductivity of these two ionic salts in acetonitrile was studied.15000charging-discharging cycles performance of supercapacitors prepared by these two kinds of ionic salts under3.0V,100C was studied.The electrolyte prepared by DMPBF4showed excellent performance in capacity and internal resistance.
