摘要
目前,大多数锂离子蓄电池中所用的电解质为LiPF6,这种电解质存在着电解液抗热性和抗水解性能差的缺点,因此研究新型的电解质迫在眉睫。研究了含氟类锂化合物作为电解质的电化学性质,并提出一种新型的电解质。实验显示,这种电解质热稳定性、倍率放电性能以及循环性能良好。总体性能优于LiPF6,是一种前景良好的电解质。
At present, LiPF6 was the widly used electrolyte in lithium ion battery. Poor performance of electrolyte resistance and hydrolysis resistance were the shortcomings of the electrolyte. So the investigation of new electrolyte was necessary. The fluorine containing lithium compounds as the electrochemical properties of the electrolyte was studied, and then a new electrolyte was proposed. Experiments show that good thermal stability, rate discharge performance and cycle performance are the advantages of the electrolyte. This electrolyte＇ s overall performance is better than LiPF6, and it has good prospects.
