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
