New Delhi: Scientists at the India Institute of Technology, Kharagpur, have developed a new nanocomposite material suitable for making storage devices called super-capacitors.

Unlike , there is no electrochemical reaction in supercapacitors. Instead, they store energy by means of a static charge and can be charged instantly. And this is why they are most sought after for applications like hybrid transportation systems and, as micro-supercapacitors, for wearable . Prepared by bringing together silver, graphene and pyrrole, the new composite has been shown to exhibit properties that could make it a good candidate for use as an electrode in such super-capacitors, according to its engineers.

Batteries have long been used to reliably store energy, but they are not preferred when repeated bursts of power need to be stored or retrieved. This is the case in cars, buses, trains, cranes, elevators and wind turbines. In these devices, they are used for regenerative braking, short-term energy storage and burst-mode power delivery – tasks that super-capacitors are better at enabling because they do not have to deal with chemical reactions and the associated changes in volume.
