摘要：

Ag coated vanadium phosphate/carbon (VPO4/C/Ag) was facilely prepared by calcination of mixture of AgNO3, VPO4/C and glucose in inert atmosphere. The SEM and TEM tests demonstrate that Ag nanoparticles are evenly distributed on the surface of VPO4/C. In the voltage range of 0.01-3.0 V, VPO4/C/Ag delivers much better rate capability, higher capacity and better cyclability than VPO4/C, which is ascribed to improvement of electronic conductivity of VPO4/C by introduction of uniformly dispersive Ag nanoparticles.
