▎ 摘　　要

Transition metal disulfides have been widely used in lithium/sodium ion batteries as cathode materials. However, the huge structural changes in electrochemical processes remain a challenge. Here, 3DG-MoS(2)hybrid nanomaterials with particular sandwich architecture were synthesized successfully by a simple evaporation and hydrothermal reaction method. This process enlarged the spacing between the graphene layers, increased the surface area, promoted electron and lithium/sodium ions diffusion, and alleviated structural deformations during ion insertion, which altogether improved the performance of lithium/sodium storage. Therefore, 3DG-MoS(2)composite nanomaterials exhibited excellent cyclic stability electrochemical performance (955 mAhg(-1)at 1 Ag(-1)after 500 cycle for LIBs; 479 mA hg(-1)at 1 Ag(-1)after 300 cycle for SIBs). When the current density gradually reduced to 100 mAg(-1), it still delivered excellent lithium/sodium storage capacity ability (1130 mAhg(-1)for lithium storage; 663 mAhg(-1)for sodium storage) even at 10 cycles of 2 Ag(-1)deep charge and discharge.
