This article introduces the basic knowledge and information of 2D transition metal dichalcogenides (2D TMDs) as electrode materials for supercapacitors (SCs), summarizes recent advances in strategies focusing on doping, structure, composition, phase, configuration, and electrolyte to improve their supercapacitor performance, and proposes future perspectives.
Recently, the development of new materials and devices has become the main research focus in the field of energy. Supercapacitors (SCs) have attracted significant attention due to their high power density, fast charge/discharge rate, and excellent cycling stability. With a lamellar structure, 2D transition metal dichalcogenides (2D TMDs) emerge as electrode materials for SCs. Although many 2D TMDs with excellent energy storage capability have been reported, further optimization of electrode materials and devices is still needed for competitive electrochemical performance. Previous reviews have focused on the performance of 2D TMDs as electrode materials in SCs, especially on their modification. Herein, the effects of element doping, morphology, structure and phase, composite, hybrid configuration, and electrolyte are emphatically discussed on the overall performance of 2D TMDs-based SCs from the perspective of device optimization. Finally, the opportunities and challenges of 2D TMDs-based SCs in the field are highlighted, and personal perspectives on methods and ideas for high-performance energy storage devices are provided. 2D transition metal dichalcogenides (2D TMDs) have attracted increasing attention as promising electrode materials for supercapacitors (SCs). In this review, basic knowledge and information of 2D TMD-based SCs are introduced, recent advances in strategies focusing on doping, structure, composition, phase, configuration, electrolyte to improve their supercapacitor performance are summarized and future perspectives are proposed.image
