The invention relates to a CuCo 2 S 4 @Ni composite material, a preparation method and application thereof, and belongs to the technical field of lithium-oxygen battery electrode materials. The technical problem solved by the present invention is to provide a CuCo 2 S 4 @Ni composite material. The material is based on foamed nickel as the skeleton, and CuCo 2 S 4 nanosheet arrays are independently grown on the foam nickel skeleton . The 4 nanosheet arrays are interconnected to form multiple pores with diameters of 200-400 nm, resulting in a novel CuCo 2 S 4 @Ni composite material with high specific surface area and good electrochemical performance, which can be used as a cathode material for lithium-oxygen batteries . The method for synthesizing the material of the present invention only uses water as a solvent and does not use an organic solvent such as isopropanol as a solvent, thereby avoiding the danger of explosion and the toxicity of the organic solvent, and is more environmentally friendly and safe. Moreover, it is synthesized by a simple hydrothermal method, and at the same time, the test period is short, the operation is easy, and the cost is low. |
