摘　　要：本文在氟化铝(AlF_3)和氟化季铵盐(M^+F^-)的摩尔比为n(AlF_3)∶n(M^+F^-)=1.2∶1,反应温度为90℃,反应时间为12h的条件下合成了四甲基铵四氟铝酸盐[(CH_3)_4NAlF_4]、四乙基铵四氟铝酸盐[(C_2H_5)_4NAlF_4]、四丙基铵四氟铝酸盐[(C_3H_7)_4NAlF_4]和四丁基铵四氟铝酸盐[(C_4H_9)_4NAlF_4],对其结构进行表征,并对其物理及电化学性质进行研究。结果表明,(C_3H_7)_4NAlF_4是一种很有潜力的低温电解质。When the molar ratio of aluminum fluoride (AlF3) to quaternary ammonium fluoride (M+F?) was 1.2:1, the reaction temperature was 90℃ , the reaction time was 12h, tetramethylammonium tetrafluoroaluminate [(CH3)4NAlF4], tetraethylammonium tetrafluoroaluminate [(C2H5)4NAlF4], tetrapropylammonium tetrafluoroaluminate [(C3H7)4NAlF4] and tetrabutylammonium tetrafluoroaluminate [(C4H9)4NAlF4] were prepared. Their structures were characterized, and their physical and electrochemical properties were studied. The results showed that (C3H7)4NAlF4 was a potential low-temperature electrolyte.
