Supercapacitor From Industrial Waste Cotton & Natural Seawater Electrolyte

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 utilised the porous carbon fibers to make high-performance supercapacitor electrodes.
For the first time, natural seawater is explored as an environmentally friendly, cost-effective, scalable, and alternative aqueous electrolyte, which may replace the existing aqueous-based electrolytes for the economic fabrication of supercapacitor.
Supercapacitor is a next-generation energy storage device that has received extensive research attention owing to advantages such as high power density, long durability, and ultrafast charging characteristic as compared to conventional capacitors and lithium-ion batteries (LIB).
