In the current effort, illustrate a different case FeNbO 4 with wolframite structure. FeNbO 4 was prepared by sol-gel polymeric precursor method in prospect of estimated prominent specific capacity. One cause is owing to the reduction of both Fe and Nb. The electrochemical lithium insertion/extraction studies on wolframite FeNbO 4 were conducted with a rate of C/10 in the potential window of 1.0-3.8V. Ex-situ XRD procedure was used to identify the Structural changes all the way through insertion/extraction of Lithium. The details of synthesis and lithium insertion mechanism in FeNbO 4 will be discussed.
