Enhancing the performance of carbon electrodes in supercapacitors through medium-temperature fluoroalkylation

Medium-temperature fuoroalkylation of microporous activated carbons (ACs) with 1,1,1,2-tetrafuoroethane is presented. Supercapacitor (SC) electrodes based on the fuoroalkylated ACs showed enhanced specifc capacitance and high specific energy in electrolytes, either aqueous potassium hydroxide solution or tetraethylammonium tetrafuoroborate-acetonitrile solution. We found … Continue reading

Super-activated biochar from poultry litter for high-performance supercapacitors

We report on the preparation of a novel hierarchically-porous super-activated carbon originating from organic waste with specific surface area exceeding 3000 m2/g, obtained starting from biochar derived by the pyrolysis of poultry litter. The chemical activation process proved to be efficient … Continue reading
