Abstract

original image

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.
