Abstract TiN fibers were prepared by electrospinning combined with ammonia reduction nitridation process using butyl titanate as the titanium source and PVP as spinning agent. The CoNiO₂/TiN composite fibers with hierarchial structure were obtained via hydrothermal method, in which the CoNiO₂ nanowires grew on TiN fibers surface. The XRD, XPS, SEM and BET results indicated that the TiN fibers had cubic phase with the diameter of about 280 nm. The CoNiO₂ nanowires with a diameter of about 10 nm were grown on the TiN fibers after hydrothermal treatment. Nickel and cobalt elements were present in the form of Ni²⁺/Ni³⁺ and Co²⁺/Co³⁺ respectively. The fibers had a mesoporous structure that the average pore size was 13.6 nm and the specific surface area was 123.8 cm²/g. The pore volume of CoNiO₂/TiN fibers was 0.4 cm³/g. The CoNiO₂/TiN composite fibers electrode exhibits the characteristics of electric double layer and pseudo capacitance. At the same time, the specific capacitance of CoNiO₂/TiN fibers reached 205.4 F/g at current density of 100 mA/g. When the power density was 66.6 W/kg, the energy density was 26.8 Wh/kg.
