Supercapacitor is an emerging and essential energy storage device to supply energy for human activities. Optimizing electrode materials is necessary for the development of high-performance supercapacitors. Herein, we synthesize different nanostructured MnO2-TiN nanotube arrays electrode materials and discuss their electrochemical performance. The synergistic effects of TiN with high conductivity and MnO2 with high capacitance can extremely enhance the electrochemical performance of the electrode material. The specific capacitance of δ-MnO2 nanosheets-TiN nanotube arrays can reach to 689.88 F•g−1 with good magnification capacity and electron/ion transport properties. Its internal resistance and the charge transfer resistance are low as 1.183 Ω and 52.23 Ω, respectively, indicating the excellent electronic conductivity and electron diffusion. In terms of charging-discharging cycle stability, the specific capacitance retention rates are 97.2% and 82.4 % of initial capacitance after 100 and 500 cycles, respectively.
