Self-Assembled 2D VS₂ /Ti₃ C₂ T_x MXene Nanostructures with Ultrafast Kinetics for Superior Electrochemical Sodium-Ion Storage.

ABSTRACT: Constructing nanostructures with high structural stability and ultrafast electrochemical reaction kinetics as anodes for sodium-ion batteries (SIBs) is a big challenge. Herein, the robust 2D VS₂ / Ti₃ C₂ T_x MXene nanostructures with the strong Ti─S covalent bond synthesized by a one-pot self-assembly approach are developed. The strong interfacial interaction renders the material of good structural durability and enhanced reaction kinetics. Meanwhile, the enlarged and few-layered MXene nanosheets can be easily obtained according to this interaction, providing a conductive network for sufficient electrolyte penetration and rapid charge transfer. As predicted, the VS₂ /MXene nanostructures exhibit an extremely low sodium diffusion barrier
