Nanomaterials have significantly better potentials for applications in the field of energy store. To achieve high energy densities at high rate capabilities, it is necessary to use innovative electrode materials with architecturally tailored nanostructures for these devices, such as batteries and supercapacitors. Heterogeneous nanostructured materials with multi-components can be tailored to address different demands for these types of novel electrodes, which are expected to exhibit synergic properties. In this presentation, the design and synthesis of hierarchical carbon nanotubes/conductive polymer/metal oxide nanoparticles ternary nanocomposites for high performance electrochemical energy storage will be reported. The performance, i.e. specific capacitance, of the fabricated supercapacitors will be shown based on cyclic voltammetry and charge-discharge measurements and compared with literature results. It is expected that the nanocomposites will effectively utilize the full potential of all the desired functions of each component.
