6 p, 2.6 MB Electroactive graphene nanofluids for fast energy storage / Dubal, Deepak P. (Institut Català de Nanociència i Nanotecnologia) ; Gómez Romero, Pedro (Institut Català de Nanociència i Nanotecnologia)
Graphenes have been extensively studied as electrode materials for energy storage in supercapacitors and batteries, but always as solid electrodes. The conception and development of graphene electroactive nanofluids (ENFs) reported here for the first time provides a novel way to 'form' graphene electrodes and demonstrates proof of concept for the use of these liquid electrodes for energy storage in novel flow cells.
