A large area mesh-like MoS2 with an expanded interlayer distance synthesized by one-pot method and lithium storage performance

Abstract

Abstract Nowadays, molybdenum disulfide is gaining increasing attention due to its unique properties and diverse areas of application. In this study, a mesh with a large area and a structure similar to that of MoS2 were synthesized using a simple one-pot synthesis method. The results revealed that irregular MoS2 nanoparticles with layer spacing (⁓0.92 nm) larger than that of the bulk MoS2 were stacked on a 3D mesh structure similar to that of MoS2 with submicron-sized macropores. And in lithium ion battery applications, the MoS2 nanoparticles obtained in this study significantly improved the electrochemical performance of an anode material. As a result of this improvement, the problems of substantial volume changes and low utilization efficiency of active materials during the charge/discharge cycle could be solved. The reversible cycle capacity of the active material gradually increased till it stabilized, and after 100 cycles, with reversible capacities of 877 and 665 mAh g−1 at 0.1 and 0.5 A g−1 were maintained and the rate performance was found to be excellent.
