Sumario: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. [Image: see text]
