The application belongs to the technical field of composite material preparation, and particularly relates to a preparation method and application of a B-NiCo2O4@NiCo-MOF composite material. Boron-modified nickel cobaltate is prepared, and is used as a precursor to prepare the B-NiCo2O4@NiCo-MOF composite material through a hydrothermal method. The electronic structure of the NiCo2O4 is regulated through B, which effectively improves the conductivity and active site exposure of the material. In combination with the porous characteristics of the NiCo-MOF, the composite material with a hierarchical structure is formed, the synergistic optimization of electronic transmission and mass diffusion is realized, and the composite material is applied to the preparation of a supercapacitor positive electrode, so that the specific capacity and rate response performance of the electrode material are improved, and the supercapacitor has high energy density and super-long service life.
