锂离子电池电解质用含硼锂盐研究进展

Research progress of boron-based lithium salts for lithium ion batteries

电解质材料是锂离子电池的关键材料之一。LiBF4、双草酸硼酸锂(LiBOB)及草酸二氟硼酸锂(LiODFB)是极具应用前景的3种含硼锂盐。介绍了3种锂盐各自的优缺点及研究近况,重点综述了它们的离子传导特性及与电极材料的相容性能。

Electrolyte is considered as one of the key materials to decide the performance of lithium ion batteries. LiBF4, lithium bis （oxalato） borate （LiBOB） and lithium oxalyldifluroborate （LiODFB） were promising boron-based lithium salts for lithium ion batteries. Advantages,disadvantages and recent developments of each lithium salt were introduced re- spectively. In addition, ionic conductivities and compatibilities with electrode materials were emphatically reviewed.
