摘　　要：本文综述了锂离子电池正、负极嵌锂材料/电解质界面膜形成功能分子的研究现状。在总结负极界面膜形成机理的基础上,根据成膜功能分子形成SEI膜的不同机理,从饰膜机制和成膜机制两个方面对现有成膜功能分子的作用效果进行了综述与评价,提出了现有SEI膜形成功能分子的不足及面临的问题。此外,简述了正极界面膜的形成机制以及正极界面膜形成功能分子的研究进展。文章最后简单介绍了理论计算方法在锂离子电池界面膜研究中的应用,并对其在设计新型成膜功能分子的应用前景进行了展望。The progress on additives of interphase films formed on anode/electrolyte and cathode/electrolyte interphases for lithium ion batteries is reviewed in this paper. On the basis of summarization of the mechanism of SEI film formation on anode surface, the performance of additives is reviewed and evaluated from two different SEI formation mechanisms, modification film mechanism and formation film mechanism, respectively. The drawback and challenge of SEI film formation additives are also illustrated. In addition, the mechanism and the progress of additives on cathode/ electrolyte interphase are briefly introduced. At the end of the paper, the application of theoretical calculation methods on interphase film is briefly reviewed, and the application of theoretical calculation methods on the design and optimization of new additives is also prospected.
