Nickel protoxide / silicon nano-wire and use thereof for preparing integrated super capacitor electrode material

The invention discloses a NiO/SiN wire and a method for preparing an integrated supercapacitor electrode material with high performance by adopting the material. The preparation method comprises the following steps: (1) the SiN wire is taken as a framework, a nickel membrane is sedimented on the SiN wire by the electroless plating technique to produce a nickel-silicon nanometer wire composite; and (2) the produced nickel-silicon nanometer wire composite is subject to rapid thermal annealing oxidation treatment. The invention adopts the advantages of the SiN wire that the scale is small, the specific surface is large, the surface atom has a large amount of nonsaturated bonds, and the tensiometric property is great, and takes the SiN wire as the framework for loading the NiO nanometer structure. The NiO/SiN wire has high specific capacitance, low equivalent essential resistance and good charging and discharging properties, is compatible with the integrated circuit technique and can be used for preparing the integrated supercapacitor electrode material with high performance.
