摘　　要：六氟磷酸锂(LiPF_6)因其突出的离子电导率、较优的氧化稳定性和较小的环境污染等优点成为目前使用最广泛的商业化锂电池电解质。由于LiPF_6热稳定性较差、价格相对昂贵,使得新型锂盐的开发与制备成为研究者们关注的热点。本文回顾了传统锂盐电解质的发展,对LiPF_6的合成工艺进行了综述,并介绍了新型锂盐的研究进展情况。LiPF6 has become the most widely used commercial lithium battery electrolyte with brilliant ion-ic conductivity,better oxidation stability and less environmental pollution etc. Because LiPF6 thermal sta-bility is poor,the price is relatively expensive,the development and preparation of new lithium salts be-come a focus of attention for researchers. In this paper,the development of traditional lithium electrolyte is reviewed,the synthesis process of LiPF6 is summarized ,and research progress of new lithium salts is in-troduced.
