Waste laboratory tissue derived porous activated carbon as supercapacitor electrode: an insight to charge storage mechanism

Waste derived activated carbon is a great alternate for the conventional carbon materials due to its low cost, abundant nature, eco-friendliness, high surface area, high porosity etc., Hence in this study, we synthesized waste laboratory tissue derived activated carbon for supercapacitor application. The as-synthesized activated carbon is characterized via material characterization techniques such as XRD, Raman, FTIR and BET. Tissue waste derived porous carbon (TAC) rendered decent electrochemical performance in IM 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 opens up new avenues for recovering and creating high-performance, environmentally friendly materials from discarded laboratory tissue. (author)
