用LiBC_2O_4F_2电解液的锂离子电池的电化学性能
Electrochemical performance of Li-ion battery using LiBC_2O_4F_2 electrolyte
摘要
Abstract
Electrochemical performance of Li-ion battery using lithium difluoro (axalato) borate(LiBC_2O_4F_2) electrolyte was studied. Cyclic voltammetry curves and AC impedance plots showed that the battery had an excellent reversibility and a lower charge transfer resistance. Charge-discharge test showed that the battery had a high initial charge-discharge specific capacity and fine cycle performance. At 25 ℃,its 0.2 C initial charge and discharge specific capacities were 135.9 mAh/g and 125.4 mAh/g, respectively. At 25 ℃ and 60 ℃,its capacity retention ratios of the 50th 0.5 C cycle were 98.7% and 92.5%,respectively.关键词
