摘要/Abstract

摘要：

在电解液中加入不同含量(5 %，10 %，20 %)的阻燃剂，研究了其对LiNi_0.4Co_0.2Mn_0.4 O₂三元材料作为正极材料组装的5 Ah锂离子软包电池的倍率性能、过充性能和短路性能的影响. 实验结果表明，电解液中5 %体积含量的阻燃剂使软包电池在1C和2C放电时，具有最好的倍率性能；当阻燃剂的体积含量提升到20 %，在过充时，电池表面温度升高的最少；在短路实验时，电池不起火、不爆炸.

关键词: 锂离子软包电池, 阻燃剂, 安全性能, 倍率性能, 过充

Abstract:

The 5 Ah soft packed lithium ion batteries with LiNi_0.4Co_0.2Mn_0.4 O₂ as the positive electrode material and the organic electrolytes with different amounts of fire retardants as the electrolyte solution were prepared. The effects of the fire retardant amount (5 %，10 %，20 %) of the fire retardants on the rate performances, short-circuit characteristics and overcharged behaviors of the 5 Ah soft packed lithium ion battery were investigated by electrochemical methods. The results indicated that the best rate performances were obtained by adding 5 vol.% of the fire retardants in the electrolyte solution when the battery was discharged at 1C and 2C. The battery had the lowest surface temperature with 20 vol.% of fire retardant in the electrolyte solution when it was over-charged. The batteries could not catch fire and explode when the battery were short-circuited.

Key words: soft-packaged lithium ion battery, fire retardant, safety performances, rate performances, over-charge.
