Abstract

Molybdenum disulfide (MoS₂) holds significant potential as a supercapacitor electrode material due to its layered structure and tunable electrical properties, though its intrinsic conductivity and cycling stability remain areas for improvement. This paper reviews the charge storage mechanisms and electrode material research progress of MoS₂ in supercapacitors. The influence of different crystalline phases—such as 2H, 1T, and 1T' —on energy storage behavior are analyzed, elucidating the working mechanisms of double-layer capacitance and pseudocapacitance. Subsequently, the current status of optimizing MoS₂ electrode performance through phase engineering, defect engineering, elemental doping, and composite structure construction is systematically summarized. Finally, challenges and future development directions in this field are explored, providing references for the design and application of high-performance MoS₂-based energy storage devices.
