Supercapacitor developed:

#GS3#science and Technology#

In search of a cost-effective material for making affordable supercapacitor devices, scientists at ARCI have converted industrial waste cotton (Trash) into highly porous carbon fibers (Treasure) by activation process and then utilized the porous carbon fibers to make high-performance supercapacitor electrodes.

What is a supercapacitor:

  • The supercapacitor is a next-generation energy storage device that has received extensive research attention.
  • Advantages: high power density, long durability, and ultrafast charging characteristic as compared to conventional capacitors and lithium-ion batteries (LIB). 
  • Among the four main components of supercapacitor electrode, electrolyte, separator, and the current collector, the first two are the pivotal components, which directly determine the electrochemical behavior of the supercapacitors. 
  • The fabrication cost of electrode materials, as well as electrolytes, should be reduced because these two components account for a major portion of the device manufacturing cost.
