本发明涉及超级电容器技术领域，特指种以Ni(NO)·6HO、Co(NO)·6HO，甘油,异丙醇和氧化石墨烯为原料来制备中空核壳NiCoO-RGO柔性超电材料，是种制备工艺简单，成本低廉的方法。本发明采用中空核壳结构的NiCoO和GO材料，通过真空抽滤法首次制备了NiCoO-RGO三明治结构复合材料，方面中空核壳结构的NiCoO具有较大的比表面积，且空心结构更利于电解液体的渗进及转移，另方面NiCoO球形结构也可以支撑开层层石墨烯之间的间距，为电解液体的流通提供了通道并可以加速电解质在材料内部的流动。这种结构的构筑可以有效的提高材料的电化学性能。 The present invention belongs to the supercapacitor technical field and relates to a preparation method of a hollow core-shell NiCo2O4-RGO flexible superconducting material. According to the preparation method, Ni(NO3)2.6H2O, Co(NO3)2.6H2O, glycerol, isopropanol and graphene oxide are adopted as raw materials to prepare the hollow core-shell NiCo2O4-RGO flexible superconducting material. The preparation method has the advantages of simple preparation process and low cost. According to the preparation method, a NiCo2O4 material of a hollow core-shell structure and a GO material are adopted, so that a NiCo2O4-RGO sandwich structure composite material is prepared for the first time through using a vacuum suction filtration method; the NiCo2O
