Abstract

Layered transition metal oxides of the formula LiMO(2) have good lithium insertion properties for which reason LiCoO(2) and LiNiO(2) have been exploited in practical lithium rocking chair batteries. Another member of the LiMO(2) series, LiFeO(2), should be an attractive cathode material considering the cheapness and environment-friendliness of iron compounds. Its rock-salt structure, however, does not allow significant amounts of lithium to be reversibly intercalated in its structure. Synthesis of layered LiFeO(2) and study of its lithium intercalating properties have been of limited success. Therefore, an attempt has been made here to study LiCo(1-y)Fe(y)O(2) solid solutions (0 <= y <= 0.4) as prospective cathode materials. XRD, FTIR, Atomic absorption spectroscopy, Particle size and Surface area analysis were carried out in this regard towards the physical characterization of the entire series of LiCo(1-y)Fe(y)O(2) compounds. The electrochemical discharge capacity of these materials is explained as a function of the iron content.
