Facile Approach to Prepare Nickel Cobaltite Nanowire Materials for Supercapacitors

Excellent electrochemical performance results from the coexistence of nickel and cobalt ions, with mesoporous characteristics and nanocrystal structure. Nickel cobalt nanowire is prepared by hydrothermal and thermal decomposition processes. High capacitance of 722 F g−1 can be obtained at 1 A g−1 in 6 M KOH, with a capacitance retention ratio of ca. 79% at 20 A g−1.
