Super-capacitor derived from Industrial waste cotton can help in energy storage: ARCI

Published: July 15, 2020

The scientists at the International Advanced Research Centre for Powder, Metallurgy and New Materials (ARCI) have developed a low-cost super-capacitor electrode made from industrial waste cotton and natural seawater has been used as an electrolyte in this process. The device can be used as an energy harvester storage device. This technology can help in doing away with other electrodes and also aqueous-based electrolytes used now.

What is a Super-Capacitor?

A super-capacitor is a next-generation energy storage device with advantages such as high power density, very long durability, fast charging characteristic, over the conventional devices in use now. There are mainly four components in the super-capacitor – Electrode, Electrolyte, Separator and Current Collector. Among these, the first two are known as the most important ones since they determine the electrochemical behaviour of the super-capacitors. These are expected to provide inexpensive storage capacity for energy needs.

ARCI came into existence in 1997 and it works as an autonomous organization under the Department of Science and Technology, Government of India. The main campus is situated in Hyderabad, Telangana and it is tasked with the development of high performance materials and processes for niche markets, demonstration of technologies at the prototype stage, etc.
