摘要
使用一种简便的水热合成方法,将废弃的甘蔗渣作为碳源,成功合成了具有垂直结构的WS_(2)@C复合材料。WS_(2)纳米片均匀地垂直锚定在甘蔗渣碳片上,提供了开放的孔道结构,作为碳基底的甘蔗渣碳片有效改善了WS_(2)材料的本征导电率,实现了良好的电接触,并有效地缓解了循环过程中的体积膨胀效应,因此在作为钠离子电池负极材料时,实现了高稳定性和高容量的电化学性能。这项工作为寻求新型高性能储能材料的设计和合成提供了有益的参考。
In this paper,WS_(2)@C composites with a vertical structure were successfully synthesised us-ing a facile hydrothermal synthesis method using waste bagasse as a carbon source.WS_(2) 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 WS_(2) 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 WS_(2) 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.
