Supercapacitors with cotton shell-derived activated carbons and porous polymer electrolyte films.

ABSTRACT: Some of the well-known challenges in the field of supercapacitors (SCs), or more specifically, electrical double-layer capacitors (EDLCs), such as low energy density and high cost, have proven to be major barriers to their widespread market success despite having some excellent electrochemical merits such as high-power density and good cyclic stability. In this work, efforts have been made to overcome these gaps and eventually enhance the performance of EDLCs via a cost-effective and eco-friendly approach. To fabricate these EDLCs, a bio-waste, namely, cotton-shell-derived activated carbons (ZnACs) (activated with ZnCl₂), was used in a mass ratio of 1 : 2 for cotton shell to ZnCl₂. This resulted in a large BET surface area of 2031 m² g^-1 a
