Due to its good charge storage in electric double layer and rapid interlayer carrier transport, molybdenum disulfide(Mo S2) with typically sandwich-like two-dimensional layered structure is a kind of ideal electrode materials for chemical power sources. In this paper, the structure and performance characteristics of Mo S2 materials were briefly introduced. Research progresses of Mo S2 materials used in chemical power sources were reviewed in recent five years. The main problems and challenges of Mo S2 nanom...
