Nickel-cobalt bimetallic sulfide (NiCo_2S_4) has a typical AB_2O_4 spinel structure. The conductivity of NiCo_2S_4 is two orders of magnitude higher than that of NiCo_2O_4,and its conductivity is 1.25 ×10~6 S·m~(-1) at room temperature. In addition,NiCo_2S_4 provides a more efficient redox reaction than the corresponding onecomponent sulfide,and has great potential for its unique nanostructures and electrochemical properties. In this paper,the preparation of NiCo_2S_4 nanostructures and its application in electrochemical energy conversion and storage are reviewed. The morphology,physicochemical properties and synthesis methods of NiCo_2S_4 nano materials are introduced. Pretreatment conditions,preparation methods and growth matrix will have an effect on the morphology and properties of NiCo_2S_4 nanostructures. NiCo_2S_4 with different nanostructures (such as nanoneedles, nanowires, nanorods, nanotubes, nanocapses, nanosheets, nanostructures and hierarchical structures) can be prepared by a variety of methods (such as hydrothermal method and solvent heat method,low temperature synthesis method,anion exchange method,steam conversion method,electrodeposition method, coprecipitation method and self-assembly,etc.). Among them,hydrothermal and solvothermal are the most commonly used methods because they have the characteristics of low cost,easy handling and suitable for large scale manufacturing. The application status of NiCo_2S_4 nano materials in electrocatalysis,supercapacitors and lithium ion batteries is summarized. This paper analyzes and compares the preparation process,method and application of different nanostructures,hoping to promote the development of NiCo_2S_4 nano materials in the field of electrochemical energy conversion and storage. The development and application direction of NiCo_2S_4 nano materials are proposed. |
