摘　　要：将非配位溶剂作为快充添加剂应用在锂离子电池中,选取了两种有结构共性的试剂,分别是六氟苯(HFB)和三氟乙酸五氟苯酯(PFTF)。从HFB和PFTF自身结构的角度分析了二者对界面溶剂化结构调控方式的不同,进而引起的脱溶剂化程度的差异,比较并分析了二者对锂离子电池快充和低温性能的影响。Uncoordinated solvents were used as fast-charging additives in lithium-ion batteries.Two kinds of reagents with common structure were selected,namely hexafluorobenzene(HFB)and pentafluorophenyl trifluoroacetate(PFTF).From the perspective of HFB and PFTF's own structure,the differences in the regulation ways of interfacial solvation structure and the resulting differences in the degree of solvation were analyzed.The effects of the two on the fast charge and low temperature performance of lithium-ion batteries were sorted out.
