Energy Storage (Supercapacitor)

The next generation energy storage device, the supercapacitor is broadly used in consumer electronics, hybrid energy vehicles, and memory back up in some electronic devices etc. Till now so many electrode materials are developed for supercapacitor applications, and they are classified according to their energy storage principles such as EDLC and pseudocapacitive types. Generally, various carbonaceous materials are treated as EDLC electrode materials and graphene having a larger surface area and higher conductivity received tremendous attention among all. Some transition metal oxides are used as pseudocapacitive electrode material due to the presence of various oxidation state. The metal atom shuttles electron transfer reaction between the electrode material and electrolyte and gives better capacitance performance. Therefore, a wider scope is lying to explore the performance and properties of new metal oxide materials and different hybrid structures for supercapacitor application.
