Abstract
HighlightsThe over-reduction from Nb5+ to Nb3+ in the lithiation process have been demonstrated to be the critical reason for the capacity decay of Nb2O5 for the first time.A novel competitive redox strategy has been proposed to suppress the over-reduction of Nb5+ to Nb3+, which can be achieved by the incorporation of vanadium to form a new rutile VNbO4 anode.The performance of VNbO4 anode designed in this study stands among the best in cycle stability.
