Abstract:
      The porous titanium nitride fibers were prepared by electrospinning combined with reduction-nitride process. The structural information of the prepared fibers can be characterized by XRD, SEM, TEM and BET. And the electrochemical feature was characterized by cyclic voltammetry and charge-discharge measurements. The results showed that the synthesized TiN continuous fiber was cubic TiN phase, and there existed abundant mesoporous structure. The specific surface area of fiber was 21.55 m2/g. The CV curves at different scan rate were similar to the rectangle. The specific capacitance was 24.03 F/g when the current density was 20 mA/g. When the current density was 50 mA/g, the specific capacitance remained above 90 % after charge-discharge measurement for 4500 times. Moreover, the power density was 0.02 kW/kg and the energy density was 3.3 Wh/kg. In summary, the porous TiN fibers have great potential application in the field of super capacitor.
