Abstract:
Graphene oxide-wrapped amorphous copper vanadium oxide is fabricated through a template-engaged redox reaction followed by vacuum dehydration. This material exhibits high reversible capacity, excellent rate capability, and out standing high-rate cyclability. The outstanding performance is attributed to the fast capacitive charge storage and the in situ formed copper with enhanced electrical conductivity.
