A\u0000lot of people are interested in supercapacitors due to their unique physical and chemical properties like eco-friendly nature, long life and high energy. It acts as a bridge\u0000between conventional capacitors, which have high power, and fuel cells/batteries,\u0000bridging the energy-power gap (having high energy storage). It is evident that there\u0000are various research initiatives to address this, and supercapacitor basic and practical\u0000research has moved quickly.

Emerging technologies are designed to reduce extraction time, increase extraction yield, eliminate the use of solvents, and lessen environmental impact.
