锂离子电池非水电解液添加剂的研究进展

Research progress of the additives in nonaqueous electrolytes of lithium ion batteries

近年来的研究表明,添加剂的使用可以显著提高电池的某些性能。综述了目前锂离子电池各种非水电解液添加剂的发展概况,并对SEI成膜添加剂、导电添加剂、阻燃添加剂、过充电保护以及改善低温性能等的添加剂的性能、作用机理和应用现状分别作了说明。

The research progress of these additives used in non-aqueous electrolyte of Li-ion batteries were reviewed in this paper. The performance, electrochemical mechanism and application status of these additives were discussed. The additives for film-forming at SEI （solid electrolyte interphase）, for conductivity, for flame- retarding, for overcharge-protecting, as well as for improving the low temperature performance of battery were described.
