[Abstract]:Ni Co double metal sulfide (NiCo_2S_4) is AB_2O_4 typical spinel structure, the conductivity of NiCo_2S_4 than NiCo_2O_4 with high conductivity by two orders of magnitude, the conductivity at room temperature is up to 1.25 * 10~6S m~ (-1). In addition, NiCo_2S_4 can provide more effective oxidation than single component sulfide corresponding reduction reaction, because the unique nano structure and electrochemical performance, has great potential in application. This paper reviewed the application of different structure of nano NiCo_2S_4 preparation and electrochemical energy conversion and storage, the morphology of NiCo_2S_4 nano materials, physicochemical properties and synthesis method. The pretreatment conditions, preparation methods and growth the matrix will have an impact on the morphologies and properties of NiCo_2S_4 nanostructures, different nanostructures (such as nano needle, nanowires, nanorods, nanotubes, nano box, nano film, nano plate and structure) The NiCo_2S_4 can be prepared by various methods (such as self-assembly and hydrothermal and solvothermal method, low-temperature synthesis method, ion exchange method, vapor conversion method, electrodeposition method, co precipitation method), which is the most commonly used hydrothermal and solvothermal method, because of their low cost, easy to handle and suitable for large-scale manufacturing. At the same time, summed up the NiCo_2S_4 nano materials in electrocatalysis, application of super capacitor and lithium ion batteries; analyze and compare the different nano structure preparation process, methods and applications, hoping to promote the NiCo_2S_4 nano materials in electrochemical energy conversion and storage areas for development; finally put forward the development direction and application NiCo_2S_4 nano materials.
