Abstract :

Supercapacitor, one the energy storage devices, of high capacity, better cyclic stability and good rate capability can be a perfect solution to fulfill the growing energy storage, harvesting and generation needs. Nanomaterials have already been proven to be efficient electrode materials in supercapacitor applications as they provide a large specific surface area and short transport/diffusion path for mass and carriers that leads to a faster kinetics and high charge–discharge capacities. These materials exploit controlled sizes, architectures, shapes, and compositions which have made them potential electrode materials in electrochemical supercapacitor applications.

In this presentation, I am presenting ongoing research activities to develop electrochemical supercapacitors using inexpensive and environmentally friendly solution-processed transition metal oxides i.e. Co3O4, NiO, MnO2, CuO and Fe2O3, Bi2O3 and V2O5 etc., as positive and negative electrode materials of different forms which are not limited to microspheres, needles, nanorods, and nanobelts morphologies. Finally, these well-controlled nanostructures were employed for assembling symmetric/asymmetric supercapacitor devices for practical demonstrations.
