In this work, ordered Ta<sub>2</sub>O<sub>5</sub> nanoparticles were synthesized by template assisted hydrothermal process. First, SBA-15 hard template was synthesized by hydrothermal process and it was used as the hard template for the synthesis of Ta<sub>2</sub>O<sub>5</sub> nanoparticles. Secondly, Ta<sub>2</sub>O<sub>5</sub> nanoparticles were synthesized simple chemical process with controlled pH condition. The crystalline and porous nature of the synthesized material was studied by powder XRD and nitrogen adsorption techniques technique, respectively. The surface morphology of the synthesized Ta<sub>2</sub>O<sub>5</sub> nanoparticles was analyzed by FE-SEM analysis. The electrochemical behavior of the synthesized Ta<sub>2</sub>O<sub>5</sub> nanoparticles was studied by cyclic voltammetry (CV), charge - discharge (CD) and electrochemical impedance techniques. The specific capacitance values of the synthesized Ta<sub>2</sub>O<sub>5</sub> NPs electrode material was calculated from galvanostatic CD technique. The synthesized Ta<sub>2</sub>O<sub>5</sub> nanoparticles electrode shows high specific capacitance and energy density value.
