This work compares for the first time the physical and chemical characteristics of activated carbons produced from glucose and hydrothermally carbonized glucose, as well as their performance as electrodes in supercapacitors in aqueous electrolyte (H2SO4). Both KOH-activated carbons exhibit similar textural properties, with BET surface areas of ~ 1400-1500 m/g and a pore volume of ~ 0.70 cm/g, t...
