Engergy Stroage & Conversion

Minimum loss storage and on-demand use of electrical energy is a basic requirement of many electronic systems. Supercapacitors and Li-ion batteries are the two most popular energy storage devices, which commonly store electricity in the form of electrochemical energy. Currently, graphite-based materials are widely used for the electrodes of those energy devices. Simply, if additional surface area is provided at the electrodes by employing CNTs or graphene, the currently available device performance could be significantly improved. In this regard, both graphene and CNT have been considered promising materials for high-performance energy-storage devices. Moreover, appropriate chemical modification for additional electrochemical activity is highly desired to enhance the energy-storage capacity.
