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…
Abstract This work presents a systematic study on how pore size and specific surface area (SSA) of carbon effect specific capacitance and frequency response behavior. Carbide derived carbons (CDC) produced by leaching metals from TiC and ZrC at temperatures from 600 to 1200 ◦C have highly tailorable microstructure and porosity, allowing them to serve as excellent model systems for porous car…
