Abstract:

A low crystalline 1T-MoS2@S-doped carbon (MoS2@SC) composite was successfully synthesized via a facile hydrothermal process. The composite is comprised by few-layer 1T-MoS2 nanosheets covered by an amorphous carbon layer with an expanded interlayer d-spacing of 1.01 nm. This structure is conducive to the fast transport of lithium-ions and volume accommodation during the charge-discharge process when the composite is applied as an anode material for LIBs. Additionally, the high conductivity and layered structure of 1T-MoS2 also facilitate fast of ion/electron transport, contributing to the improvement of the electrochemical properties. Therefore, this material demonstrated a high rate performance and excellent cycling stability, with the capacities of 847 and 622 mA h g(-1) achieved at the current densities of 0.2 A g(-1) and 2 A g(-1), respectively. Even at a larger current density of 2 A g(-1), MoS2@SC delivered a high reversible capacity of 659 mA h g(-1) with an average capacity loss of 0.006% per cycle after 500 cycles.
