A B S T R A C T Electrical double layer capacitors (EDLCs) with activated sucrose-derived carbons (ASCs) as electrodes are reported. The carbons were prepared by the pyrolysis of sucrose followed by the activation with CO2 gas for 1–5 h at 900 -C to tune the pore size distribution and the specific surface area (SSA). The porosity of the ASCs has been characterized using N2 and CO2 adsorp…
