The Preparation and Electrochemical Properties of Vertically Structured WS2@C Composites
In this paper,WS2@C composites with a vertical structure were successfully synthesised us-ing a facile hydrothermal synthesis method using waste bagasse as a carbon source.WS2 nanosheets were uniformly anchored vertically on the bagasse carbon sheets,providing an open pore structure,and the bagasse carbon sheets as a carbon substrate effectively improved the intrinsic conductivity of the WS2 material,achieving good electrical contact and effectively mitigating the cycling.The open pore structure of the bagasse carbon sheet as a carbon substrate effectively improves the intrinsic con-ductivity of the WS2 material,achieves good electrical contact and effectively mitigates the volume ex-pansion effect during cycling.As a result,high stability and high capacity electrochemical properties were achieved when used as anode materials for sodium ion batteries.This work provides a useful ref-erence in the search for the design and synthesis of new high-performance energy storage materials.
