Flexible and highly scalable V2O5-rGO electrodes in an organic electrolyte for supercapacitor devices
Vanadium pentoxide–reduced graphene oxide (rGO) free-standing electrodes are used as electrodes for supercapacitor applications, eliminating the need for current collectors or additives and reducing resistance (sheet resistance 29.1 Ω □−1). The effective exfoliation of rGO allows improved electrolyt...
