摘要：

MoS2/Ti3C2Tx composite was synthesized by a facile one-step hydrothermal method without further annealing process. When tested as anode material for sodium-ion batteries, it exhibited a high reversible capacity of 331 mA h g(-1) at 100 mA g(-1) after 70 cycles with only 0.058% decay per cycle. When tested as anode material for lithium-ion batteries, it exhibited a reversible capacity of 614.4 mA h g(-1) at 100 mA g(-1) after 70 cycles with only 0.05% decay per cycle. Moreover, compared with pristine MoS2 and pure Ti3C2Tx, the composite had better rate performance and faster ion diffusion kinetics, which might be caused by the as-prepared composite material having relatively rough surface, more active sites and more convenient diffusion paths.
