α-MoO3: A high performance anode material for sodium-ion batteries

Abstract Sodium storage in α-MoO 3 anode material is reported here for the first time. Upon cycling in the voltage window 0.04–3.0 V, MoO 3 anode delivers first cycle sodiation and desodiation capacities of 771 and 410 mAh g − 1 . The average sodiation and desodiation potentials of the stable cycles lie below 1.0 V with attractive voltage profiles. MoO 3 anode also shows favorable rate performance and long cycle life over 500 cycles.
