摘要:

商业化锂离子电池使用的负极材料主要是石墨,在未来的一段时间内石墨仍是主要的负极材料。锂离子电池石墨电极在使用或运输过程中常会出现某些失效,这些失效将影响锂离子电池的使用寿命,因此如何延长锂离子电池石墨电极的使用寿命成为重中之重。通过对近期相关文献的探讨,综述了锂离子电池石墨电极主要的失效机理,然后根据石墨电极的失效机理从材料设计与电极设计两个方面来延长石墨电极的使用寿命,最后指出未来长寿命石墨电极的未来发展趋势。

Abstract:

Graphite is the main anode material used in commercial LIBs, and graphite will remain the main anode material in the future. Failures often occur during the use or transportation of the LIB graphite electrode. These failures will affect the service life of an LIB. Therefore, how to extend the service life of the LIB graphite electrode becomes the most important issue. This article, as well as the recent relevant literature, summarizes the main LIB failure mechanism of the graphite electrode. Then, according to the failure mechanism of the graphite electrode material and the electrode design, two aspects are proposed to prolong the service life of the graphite electrode. Finally, the future development trend of the long-life graphite electrode is suggested.

Key words: lithium ion battery, graphite electrode, long life, failure mechanisms
