The iron tungstate materials Fe 2W y O 3( 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 Fe 2WO 6, Fe 2W 3O 12 and nano-composite Fe 2WO 6/WO 3 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 Fe 2WO 6 sample.
