Preparation of ZnNbO anode material for high-performance lithium/sodium-ion batteries.

Niobium-based oxides (M-Nb-O) as promising lithium/sodium-ion storage anode materials have attracted much attention. More types of niobium-based oxides are prepared in order to provide more candidates for anode materials. Herein, ZnNbO as a novel intercalation-type anode material has been reported for the first time.
