MoS2块体材料的电子传输性能差，离子在其层间扩散缓慢，限制了其法拉第准电容的充分发挥。针对上述问题，本项目拟从改变晶体结构出发，通过剥离MoS2至原子薄层，使其从半导体转变为具有金属或准金属特性的材料，本质上提高其导电能力和反应活性。本项目将对原子薄层MoS2的特征超电容行为进行系统研究，探讨电荷存储机制；并以此为指导，建立基于原子薄层MoS2的多级复合电极材料的合成方法，在保留原子薄层MoS2高导电性和丰富活性位的基础上发挥复合材料的协同作用，解决MoS2法拉第准电容低、倍率性能差的主要问题。通过开展本项目研究，将对过渡金属硫化物电极材料超电容行为形成系统认识；同时，深入理解并掌握原子薄层MoS2纳米复合材料的可控制备、微观结构调控、超电容性能优化以及相关机理，将为开发高效、经济的新型超级电容器电极材料，实现高能量密度与高功率密度的协调统一提供参考和指导。

The low conductivity and limited diffusion of ions result in poor performance of MoS2 as electrode materials for supercapacitors. To address these issues, this project aims to fundamentally increase the conductivity and electrochemical activity by exfoliating MoS2 to several or single layer(s). The project will systematically explore the supercapacitive behavior and charge storage mechanism of atomic layered MoS2; set up methodology for fabricating highly-dispersive atomic layered MoS2 based composites with excellent conductivity and reaction activity to achieve high faradic pseudocapacitance and good rate capability. Through the project, system knowledge of the electrochemical behavior of transition metal sulfides in supercapacitors will be established, at the same time, the synthesis, structure control, charge storage mechanism and optimization of the supercapacitive performance will be comprehended, which will offer a reference and guidance for the research and development of novel electrode materials for supercapacitors to achieve both high power density and energy density.
