Research progress of limiting voltage additives for lithium ion batteries

限压添加剂(过充保护添加剂)与锂离子蓄电池的安全性密切相关,正在成为锂离子蓄电池电解液重要的添加剂成分。阐述了锂离子蓄电池有机电解液限压添加剂的研究现状,探讨了不同种类的限压添加剂对锂离子蓄电池过充电保护的作用机理,比较了不同限压添加剂的氧化电位、作用效果及其对锂离子蓄电池性能的影响。

Limiting voltage additives （overcharge protection additives） are closely related with the safety of lithium ion batteries. This paper discussed the current status of different limiting voltage additives used in lithium ion batteries. The working mechanism, oxidation potential, limiting voltage efficiency and the impacts of each limiting voltage additive on the battery＇s performances were compared.
