The general synthesis of Ag nanoparticles anchored on silver vanadium oxides: towards high performance cathodes for lithium-ion batteries

A general strategy has been developed for the one-pot synthesis of Ag nanoparticles uniformly anchored on silver vanadium oxides (SVOs) including AgVO3, Ag2V4O11, Ag0.33V2O5 and Ag1.2V3O8. All the resulting Ag/SVO hybrids demonstrated excellent lithium ion electrochemical intercalation properties, due largely to the improvement in conductivity with the introduction of silver nanoparticles, the large accessible surface area and possible catalytic effects. For instance, the as-prepared Ag/AgVO3 hybrid exhibits a superior rate capability, with a high discharge capacity of 199 mA h g(-1) even at a rate of 5 A g(-1).
