dc.description.abstractGraphene–molybdenum dioxide composites in several ratios have been prepared through a facile synthesis method. Depending on the ratio, the as synthesized composites have either 2-dimensional graphene sheets with MoO2 particles anchored to them or a clustered agglomerate morphology. The composites have been characterised using Raman spectroscopy, X-ray diffraction, and electron diffraction to confirm the monoclinic MoO2 phase that is present. Lithium storage properties of the as-synthesised samples were tested in a coin-type half cell assembly to determine the relationship between the ratio and the electrochemical performance. The sample with highest amount of MoO2 (78 wt%) displayed the most promising lithium storage properties, with stable cycling performance at 0.2 A g−1 that shows negligible capacity loss over 50 cycles, retaining a capacity of 640 mA h g−1. The rate capabilities were also tested, and show a capacity of 380 mA h g−1 at 2.0 A g−1, which is comparable to the theoretical capacity of graphite and previously reported work on similar materials.-
