摘　　要：随着动力新能源和高端电子产品等新领域的飞速发展,锂离子电池因其各项优异的性能得到了广泛应用。由于传统的锂离子电池的热稳定性不好,电池在充放电的过程中会发生热失控而燃烧,进而发生爆炸。本文首先介绍了几种不同的锂电池阻燃隔膜,相比于传统隔膜,阻燃性能更加明显,然后从阻燃添加剂及其结构改进方面介绍了阻燃性电解液的性能优势。因此研发应用阻燃功能的锂电池隔膜和电解液,改善锂电池的安全性能成为目前研究热点。With the rapid development of power new energy and high-end electronic products,lithium ion battery has been widely used for its excellent performance.Due to the poor thermal stability of traditional lithium-ion battery,the battery will burn out of control during charging and discharging,and then explode.Several different flame retardant separators for lithium batteries were introduced,compared with traditional separators,the flame retardant performance was more obvious.Therefore,research and application of flame retardant lithium battery separator and electrolyte to improve the safety of lithium battery had become a hot topic.
