NiMoO 4 /MoO 3 (NMO) was synthesised by the sol–gel method. The structural properties of the synthesised composite were studied using XRD and Raman analysis. The structural and morphological effects on the addition of NiMoO 4 to α-MoO 3 matrix were analysed. The prepared sample was used as an anode material in Li-ion battery. The cycle stability and charge discharge performance of NMO was compared with pure mesoporous MoO 3 anode. The NiMoO 4 /MoO 3 anode exhibited first discharge capacity of 1031 mAh/g and a reversible capacity of 324 mAh/g after 50 cycles. This material is an encouraging candidate for high-performance LIBs anode.
