Abstract:Hierarchical nanostructured activated carbon electrode material was prepared from the used-coffee
grounds to fabricate a cost-effective, scalable and high-performance symmetric supercapacitor. The
interconnected, disordered and microporous material was synthesized in a simple two-stage method
of chemical activation with zinc chloride followed by direct pyrolysis of the coffee grounds at 900 ºC
in nitrogen atmosphere. The N2 adsorption and desorption analysis showed that the prepared material had
an extraordina… Show more
