An-All-Solid State Supercapacitor Device from E-Waste Derived Activated Carbon

Abstract

Recycling solid waste has substantial economic and environmental advantages. Electronic waste (e-waste) has the complex intrinsic trait of combining metals and non-metals contained in the same waste stream, which limits the recycling technologies that are now available for it. Much interest has been created by the outstanding surface and conductive qualities of carbon-based materials made from waste. In this article, we transformed e-waste (end of life keyboard) into highly porous activated carbon for its application as high-performance electrode material for supercapacitor. The as-synthesized activated carbon is characterized via material characterization techniques such as XRD, Raman, FTIR and BET. E-waste derived porous carbon (EWPC) rendered decent electrochemical performance in 1M H2SO4 electrolyte. Furthermore, an-all-solid-state symmetric supercapacitor device (EWPC//EWPC) has been fabricated and recorded convincing results in terms of energy density, power density, and cyclic stability. Hence, this study open up new avenues for recovering and creating high-performance, environmentally friendly materials from discarded e-wastes.
