Article Highlights Basswood-derived free-standing thick carbon electrodes were developed for supercapacitors. The capacitance performance was enhanced by pre-oxidation, solvothermal treatment and KOH activation. Supercapacitors assembled from the optimized electrode exhibited good rate performance and stability.
