Abstract:

The thermal stability of 1M LiPF6, LiClO4, LiN(SO2CF2CF3)2 (LiBETI) and LiPF3(CF2CF3)3 (LiFAP) solutions in mixtures of ethylene
carbonate, diethyl carbonate and dimethyl carbonate in the temperature range 40350 8C was studied by ARC and DSC. NMR was used to
analyze the reaction products at different reaction stages. The least thermally stable are LiClO4 solutions. LiPF3(CF2CF3)3 solutions showed
higher thermal stability than LiPF6 solutions. The highest thermal stability was found for LiN(SO2CF2CF3)2 solutions. Studies by DSC and
pressure measurements during ARC experiments with LiPF6 and LiFAP solutions detected an endothermic reaction, which occurs before a
number of exothermic reactions as the temperature increases. Fluoride ions are formed and react with the alkyl carbonate molecules both as
bases and as nucleophiles. 锂离子电池电解液安全性能测试仪-ARC(加速绝热量热仪) 加速量热仪(ARC)
