In this work, we studied the possibility of using the Fe 6+-"super iron"-type compound, K2FeO 4, as a potential cathode material for rechargeable Li batteries and its behavior in several types of non-aqueous solutions was investigated. Classical electrochemical techniques such as cyclic voltammetry and chronopotentiometry combined with photoelectron spectroscopy (XPS), X-ray diffraction (XRD), Mössbauer spectroscopy, atomic adsorption (AA) and atomic emission (AE) have all been used in order to obtain a full picture of the electrochemical behavior for this compound.
