络合法制备LiPF6的电化学性能
The Electrochemical Performance with LiPF6 of using complexometry
【摘要】 六氟磷酸锂(LiPF6)具有良好的导电性、电化学稳定性,是目前和将来锂离子电池电解质的最佳选择之一。本文采用络合法制备电解质材料LiPF6,研究了LiPF6应用于锂离子电池和标准正极材料LiCoO2组装成电池的充放电及循环性能。自制电解液组装的电池充放电容量高、充放电循环效率稳定在88%左右,表明LiPF6具有良好的脱锂、嵌锂性能,良好的充放电性能和循环性能。
【Abstract】 As the electrolyte of lithium ion battery with fine conductivity,and electrochemical stability,LiPF6 is the best choice of electrolyte in lithium ion battery.In this paper,we used complexometry to prepare LiPF6 electrolyte.The charge and discharge performance and cycle performance of the assembled battery were investigated with LiPF6 as electrolyte and LiCoO2 as anode material.The cell assembled with the LiPF6 sample showed fine charge capacity and discharge capacity.Moreover,charge and discharge cycle efficiency stabilized at 88%,which indicated that our sample had fine take-off and take-in lithium performance and fine charge and discharge performance,as well as fine cycle performance.
