Included angle adjustable copper bell-shaped WS2/C amorphous material as well as preparation method and application thereof

The invention belongs to the technical field of controllable preparation of transition metal sulfur compound materials, and relates to controllable preparation of sodium ion battery electrode materials, in particular to an included angle adjustable copper bell-shaped structure WS2/C amorphous material and a preparation method and application thereof. By controlling the volume ratio of a water-oil two-phase solution, an oil-in-water-balance-water-in-oil micelle confinement microemulsion synthesis strategy is provided, the WS2/C amorphous material with an included angle adjustable (25-180 degrees) copper bell-shaped structure can be controllably prepared by means of step-by-step heat treatment, and the prepared negative electrode material has high-rate (10A. G ) sodium storage performance. 本发明属于过渡金属硫化合物材料的可控制备技术领域，涉及钠离子电池电极材料的可控制备，特别指一种夹角可调铜铃状结构WS2/C非晶态材料及其制备方法与应用。本发明通过控制水油两相溶液的体积比例，提出了"水包油-平衡-油包水"的胶束限域微乳液合成策略，借助逐级热处理手段，可控制备出夹角可调（25-180度）铜铃状结构的WS2/C非晶态材料，制备的负极材料具有高倍率（10A·g-1）储钠性能。
