Abstract:
A 3D tricontinuous Na3 V2 (PO4 )3 :reduced graphene oxide-carbon nanotube cathode is directly deposited on the current collector without any conductive additives or binders by a facile electrostatic spray deposition (ESD) technique. Such an electrode displays excellent rate capability and long cycling stability, which is rather typical of supercapacitors but is connected here with the much higher energy density of an efficient battery electrode.
