Super capacitor electrodes from waste

The Scientists at International Advanced Research Centre for Powder Metallurgy & New Materials (ARCI) have utilised Tamarind seeds and cotton waste to make low-cost super capacitors for energy storage.
They have converted waste materials into highly porous carbon fibres by activation process.
Then these porous carbon fibres are utilised to make high-performance super capacitor electrodes.
It can pave way towards affordable electric vehicles and hybrid vehicles which bank on super capacitors for their application in braking systems and start-stop cycles.
Super capacitors are high-capacity capacitors that store electrical charge or electrochemical energy.
