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

Sodium storage in alpha-MoO3 anode material is reported here for the first time. Upon cycling in the voltage window 0.04-3.0 V, MoO3 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. MoO3 anode also shows favorable rate performance and long cycle life over 500 cycles. (c) 2013 Elsevier B.V. All rights reserved.
