V2O5 Loaded on SnO2 Nanowires for High-Rate Li Ion Batteries

A simple gas-phase-based method is employed to coat V2O5 on SnO2 nanowires. An electrode made from the SnO2/V2O5 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.
