Abstract
The invention relates to a mixed-phase oxide for use as an active electrode material. e.g. in lithium-ion or sodium-ion batteries. The mixed-phase oxide comprises Nb and Ti and further comprises M(III) and/or M(II); wherein M(III) is selected from Cr, Al, Ga, and mixtures thereof; M(II) is selected from Zn, Cu, Mg, and mixtures thereof; wherein the mixed-phase oxide comprises an interpenetrating mixture of a first phase and a second phase; wherein the first phase has the crystal structure of TiNb2O7 and the second phase has the crystal structure of Zn2Nb34O87.
