摘要/Abstract

摘要：

近年来关于锂离子电池造成的安全问题甚至事故的报道屡见不鲜，锂离子电池的安全问题已经成为人们关注的焦点. 我们用四丁基六氟磷酸铵（TBAPF₆）作为锂离子电池电解液阻燃添加剂，研究发现添加了TBAPF₆的电解液具有明显的阻燃效果，同时电解液电导率下降并不明显. LiCoO₂/Graphite全电池在添加了TBAPF₆的电解液中可逆容量会略有降低，但具有更优异的循环稳定性. 主要是由于TBAPF₆添加量的增加会影响石墨电极的库伦效率，延长活化时间. 通过对LiCoO₂/Graphite全电池绝热加速量热仪（ARC）测试，表明添加TBAPF₆对电池的燃烧有明显的抑制作用. 在TBAPF₆添加量至5%时，电池在300 ^oC内自放热速率不超过0.1^oC/min，电池的安全性显著提高.

Abstract: Safety issues have been attracted more and more attentions due to the wide applications of lithium ion batteries. Introducing flame retardant additives are one of the effective strategies to improve the safety of lithium-ion batteries. In this paper, the tetrabutylammonium hexafluorophosphate (TBAPF₆) as a flame retardant additive was added to the electrolyte as a flame retardant additive to enhance the safety of lithium ion batteries. The self-extinguishing time (SET) and ionic conductivities of the electrolytes with different TBAPF₆ contents were investigated. It is found that TBAPF6 dramatically reduced the flammability of the electrolyte while slightly decreasing ionic conductivitiesconductivity. The electrochemistry electrochemical performances of graphite half cells with higher content of TBAPF₆ showed poor compatibility between TBAPF₆ additive and graphite anode due to the lack of stable SEI layer formation. But However, the LiCoO₂/Graphite graphite full battery with 5% TBAPF₆ showed good electrochemical performance and extraordinary thermal stability within 300 ^oC, representing demonstrating a good flame retardant additive of TBAPF₆.
