Recently, the increasing demand for sustainable clean energy from non-fossil sources motivated the researchers in energy storage devices and supercapacitors are one of the most promising energy storage systems. In this study, flexible copper and nickel coated electrodes are fabricated for supercapacitor applications from Ethaline deep eutectic solvent media. Copper and nickel-based materials were potentiostatically electrodeposited on flexible graphite substrates from Ethaline ionic liquid containing copper and nickel ions. Cu–Ni coated graphite films were scanned in 1 M KOH from
