A simple gas‐phase‐based method is employed to coat V 2 O 5 on SnO 2 nanowires. An electrode made from the SnO 2 /V 2 O 5 core/shell‐nanowires delivers a high power density of about 60 kW kg −1 while the energy density remains 282 W h kg −1 . In addition, the electrode exhibits very‐good cycling stability. Such good performance shows very‐promising potential in the application of a high‐rate lithium battery.
