Lithium ⁃ion batteries (LIBs) have been widely utilized in portable electronic devices due to their high energy density, long cycle life, and convenience of use. The graphite of commercial LIBs cannot meet the new commercial demand due to the low theoretical specific capacity and poor safety. Cobalt sulfide has attracted wide attentions as anode materials due to its high specific capacity and good thermal stability. This review summarized the defects of cobalt sulfide compounds (CoS, CoS2, Co3S4, Co1-xS, Co9S8) and the research progress in their modification for LIBs electrode materials. And the perspective of cobalt sulfide electrode materials was also discussed.
