N2 - The iron tungstate materials Fe2WyO3(y+1) (y = 1 and 3) have been synthesized by a low temperature route, and their lithium insertion properties measured using galvanostatic and EVS measurements. This paper reports the lithium insertion into Fe2WO6, Fe2W3O12 and nano-composite Fe2WO6/WO3 materials made by this co-precipitation route. Relatively high initial discharge capacities were observed for all materials, the highest being 653.9 mAh g−1 for the y = 3 material heat treated at 500 °C. Rapid capacity fade behaviour was observed for all materials prepared at 500 °C. Improved performance was determined for the iterations heat treated at 950 °C with a reversible specific capacity of 320 mAh g−1 observed for the Fe2WO6 sample.
