摘　　要：目前商业化锂离子电池常用的锂盐LiPF6,对水极其敏感,热稳定性差,尤其是在高温条件下的应用存在着一定的安全隐患.种类多且环境友好的新型有机硼酸锂盐越来越受到人们的重视.本文综述了近年来几种锂盐的合成方法,电化学性能,各自存在的优点和不足以及本课题组在聚合硼酸锂盐方向取得的系列研究进展,并对锂盐和聚合物电解质的发展方向进行了展望.The commercial lithium salt LiPF6 is extremely sensitive to moisture and easy to thermally decompose, which causes a catastrophe especially under high temperature conditions. The lithium borate salts with highly thermal stability and environmental benignancy have been developed and received extensive attention. Research progress of some lithium borate salts including a series of single ion polymeric lithium borate salts as to their synthetic strategies, electrochemical properties, advantages and disadvantages were reviewed in this paper. The perspective concerning application of these lithium borate salts in next-generation lithium batteries was discussed as well.
