Fe2(MoO4)3 microspheres as a potential anode material for lithium ion batteries

Abstract

Fe 2 (MoO 4 ) 3 microspheres are fabricated by a facile hydrothermal process assembled from Fe 2 (MoO 4 ) 3 nanoplates. The microstructures and morphologies of the Fe 2 (MoO 4 ) 3 nanorods was characterized using powder X-ray diffraction (XRD) and scanning electron microscopy (SEM). The discharge capacity of Fe 2 (MoO 4 ) 3 microspheres show a larger initial capacity of 1169 mAh/g and still retains a high capacity of 670 mAh/g, even after 80 cycles. More importantly, when the current density increased to 500 mA/g, it can render reversible capacity of 449 mAh/g even after 50 cycles, indicating its potential applications for next-generation high power lithium ion batteries (LIBs).
