Study on Electrochemical Performance of Wire Mesh Sulfur Nickel and Cobalt Metal Compounds

Wire mesh three-dimensional network structure of NiCo₂S₄ on nickel foam substrate was prepared by two steps hydrothermal method, and its electrochemical performances were investigated.Resultsshowed that NiCo₂S₄@the nickel foam had high area of specific capacitance, when the current density was 10 m A/cm², the area of specific capacitance was up to 2.87 F/cm²; when the current density increased from 10 m A/cm² to 50 m A/cm², capacitance retention still remained at 60. 9%, showing excellent ratio of performance, when the load was 6. 21 mg/cm² and the material was charged and discharged for 1 000 cycles at 30 m A/cm², the capacitance retention was 67. 3%.
