▎ 摘　　要

Nano-MoS2 and MoS2/graphene nanocomposites are prepared by a simple xylitol auxiliary ball milling method. Xylitol can increase the shear force in the ball milling process and overcome the interlayer van der Waals force between MoS2 and the graphite layer, thus improving the efficiency of preparing nanomaterials by ball milling method. As a result, the MoS2/graphene hybrid nanosheets exhibit higher discharge capacity and better cycle stability as lithium-ion anode materials. When the original addition amount of MoS2 and graphite is 1:1, the materials have the best electrochemical behaviors. The initial discharge capacity is as high as 1014 mAh.g(-1) at a current density of 50 mA.(-1), after 300 cycles at a current density of 250 mA.g(-1), the capacity remains at 664 mAh.g(-1) without decay. Therefore, the xylitol auxiliary ball milling method is suitable for the scalable preparation of new transition metal sulfide (TMDS)-based anodes for lithium-ion batteries.
