Growth and studies of Li(Mn, Co_ oxides for battery electrodes

摘要

There is interest in lithium intercalation oxide materials for cathodes in rechargeable batteries. We have synthesized LiMO_x, (where M chemical bounds Mn, Co) by a less expensive solution route. Reagent grade acetates or hydroxides as prescursors for lithium, manganese, and cobalt, respectively, with methoxy ethenol and acetic acid as solvents were used. Powers with different compositions were acieved at annealing temperature below 700 deg C. Thin films were deposited by spin coating. X-ray diffraction, Raman spectroscopy, and impedance spectroscopic results are presented. These studies indicate that this synthetic route is suitable to produce good quality lithium-based oxides useful for cathode in lithium-ion rechargeable battery.
