ersibly lithium in the tunnels. This material exhibit three voltage plateaus at 2.3, 1.5 and 0.7 V and has an over all discharge capacity of 1100 mAh/g. When cycling in the 2-V region, the material exhibits high capacity of 275 mAh/g and very good cyclic reversibility. X-ray photoelectron spectroscopy of the discharged material showed that iron is reduced to the divalent state, and the lithium incorporated in the tunnels is purely ionic. This result explains the good reversibility of this electrode material. When of two conducting polymers, polyaniline and polypyrrole, could result in much improved physical properties with respect to their applciations in pH electrodes and conducting paints/coatings. However, the composite has time dependant propertie that ma
