Application progress of metallic phase of molybdenum disulfide for energy storage and conversion

Abstract

The metallic molybdenum disulfide exhibits large interlayer spacing, high electrical conductivity and abundant active sites, which shows wildly application prospects in the field of energy storage and conversion. The recent progress of metallic molybdenum disulfide in energy storage and conversion was reviewed. Firstly, the crystal and electronic structure of the metallic molybdenum disulfide were introduced, and the synthesis methods such as top-down (lithium intercalation stripping) and bottom-up (solvent/hydrothermal) were included. Then, the progress of metallic molybdenum disulfide and its composites in the fields such as hydrogen evolution reaction, lithium (sodium) ion batteries and supercapacitors were summarized. Finally, it is pointed out that the current challenges of metallic molybdenum disulfide are uncontrollable synthesis process and poor structural stability. The in-depth study on the structure and properties of metallic molybdenum disulfide is expected to fundamentally improve its performance and practical application in the field of energy storage and conversion.
