The hierarchically lithiated MoO 3 microspheres composed of primary crystallized particles have been prepared in the absence of surfactant. The surface morphologies of the lithiated MoO 3 structures can be well regulated through adjusting the adding amounts of ethanol during their synthetic process. The results of XRD patterns and the elemental analysis indicated the decrease of lithium content with the increase of ethanol feeding amount. The obtained lithiated MoO 3 samples showed the initial capacities of nearly 300 mAh/g at 30 mA/g and 41.8 mAh/g at 200 mA/g. Therefore, this work has showed a facile way to fabricate the lithiated MoO 3 cathode materials with controllable surface morphology and lithium content.
