Abstract

As a part of our on-going study on silver vanadium phosphorous oxides (Ag_xV_yO_zPO₄), we report here the first study of the electrochemical reduction of a low Ag/V ratio silver vanadium phosphorous oxide, Ag_0.48VOPO₄·1.9H₂O. Reminiscent of Ag₂VO₂PO₄ reduction, in situ formation of silver metal nanoparticles along with an associated increase in conductivity were observed after reduction of Ag_0.48VOPO ₄·1.9H₂O with 0.37 electron equivalents. However, in contrast to our lithium/Ag₂VO₂PO₄ cells, our lithium/Ag_0.48VOPO₄·1.9H₂O cells displayed an even higher voltage on discharge and a characteristic multi-plateau voltage profile, where vanadium reduction was the first reduction step.
