| 摘 要： | 合成了1-乙基-3-甲基咪唑四氟硼酸(EMIBF4)和1-丁基-3-甲基咪唑四氟硼酸(BMIBF4),并采用DSC、线性扫描伏安等方法对它们的性能进行了研究.两种离子液体的电化学窗口在4.3 V左右.以EMIB4 1.0 mol/L LiPF6 5%亚乙烯碳酸酯(VC)为电解液的中间相炭微球(MCMB)/LiCoO2实验电池,在50次循环(C/15)后仍有91 mAh/g的放电比容量,表现出一定的循环能力.

| Abstract: | 1-ethyl-3-methylimidazolium tetrafluoroborate(EMIBF4) and 1-butyl-3-methylimidazolium tetrafluoroborate(BMIBF4) were synthesized and their performance was investigated by DSC,linear sweep voltammetry methods.The potential windows of two ionic liquids were both 4.3 V approximately.The mesocarbon microbeads(MCMB)/LiCoO2 experimental batteries using EMIBF4 1.0 mol/L LiPF6 5% vinylene carbonate(VC) as the electrolyte had the specific discharge capacity of 91 mAh/g after 50 cycles(C/15).The battery showed certain cycle ability. |
