Real-Time NMR Studies of Electrochemical Double-Layer Capacitors

Abstract

11B NMR spectroscopy has been used to investigate the sorption of BF4– anions on a highly porous, high surface area carbon, and different binding sites have been identified. By implementing in situ NMR approaches, the migration of ions between the electrodes of the supercapacitors and changes in the nature of ion binding to the surface have been observed in real time.
