锂离子电池负极表面膜的研究现状

Research status of solid electrolyte interface of anode in lithium ion batteries

综述了锂离子电池负极材料表面固体电解质界面膜(SEI膜)的研究现状。在总结SEI膜的组成和特性、形成的机理及模型的基础上,分析了SEI膜可能的影响因素,讨论了SEI膜的质量对电池的热稳定性和可逆性特性的影响。

The progress on additives of interphase films formed in anode/electrolyte interphases for lithium ion batteries was reviewed. On the basis of summarization of the characterization and mechanism of SEI film formation on anode surface, the possible effect factors on the SEI film were given. The safety performance, such as thermal stability and reversibility were highly dependent on the quality of the SEI.
