摘要: 锂离子电池(LIBs)因具有能量密度高、循环寿命长以及使用方便等优点,已经广泛应用于便携式电子设备。然而,商业化锂离子电池负极石墨的理论比容量低、安全性差,不能满足市场新的需求。硫化钴负极材料因其高的比容量和良好的热稳定性引起了研究者广泛的关注。概述了锂离子电极材料硫化钴化合物(CoS、CoS2、 Co3S4、Co1-xS、Co9S8等)存在的缺陷及改性研究进展,对硫化钴负极材料的未来研究方向也进行了展望。

Abstract: 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.

Key words: Lithium?ion batteries, Cobalt sulfide, Morphology control, Conductive coating, Oxide coating, Element doping
