Development of inexpensive and high performance electrodes based on three-dimensional (3D) nanostructures (nanotube arrays) potentially useful for supercapacitor applications by adopting nano-porous templates assisted synthesis will be demonstrated here. The nano-porous templates we used to synthesize electrodes include highly ordered alumina and titania membranes. The deposition of MnO2 on well ordered and tailored templates and its modifications ease to fabricate regimented supercapacitor electrodes having immense surface area and superior ion diffusion properties for the enhanced charge storage along with high rate capability and cyclic stability. The improved energy storage properties of such 3D electrodes would be extremely useful for the development of light, compact and high performance supercapacitors for a variety of high power demanding stationary and portable applications.
