摘要
使用一种离子液体[1-乙基-3-甲基咪唑金翁四氟硼酸盐(EM IBF4)]掺杂极性聚合物-偏氟乙烯/六氟丙烯共聚物[P(VDF-HFP)],制备了固态聚合物电解质,其热分解温度达到273℃,30℃的离子电导率达到1-0 4S/cm数量级,对铝集流体具有较好的电化学稳定性。
A kind of ionic liquid, 1-ethyl-3-methylimidazolium tetrafluoroborate(EMIBF,) was used as plasticizer for polar polymerpoly (vinylidenefluoride-co-hexafluorpropylene)[P(VDF- HFP)7. The pyrogenation temperature of this polymer electrolyte adds up to 9.73 ℃. It possesses the ionic conductivity up to the magnitude order of 10^-4 S/cm at 30 ℃. In this paper the effect of amount of lithium salt on ionic conductivity was investigated by electrochemical method. It suggested a possible mechanism for the influence of lithium salt on the ionic conductivity for polymer electrolytes. Moreover, the electrochemical stability of polymer electrolyte was good with respect to Al substrate.
