Abstract
Lithium intercalation materials are of special interest for cathodes in rec hargeable batteries. We used a novel chemical solution-based route for the synthesis of Li(Mn, Co, Ni) oxides, and their thin films were deposited by spin coating. Films of LiMnxNi1-xO2, LiMn2-xCoxO4, and LiNi1-xCoxO2 were de posited by spin coating from the solution at a comparatively lower substrat e temperature similar to 600 degreesC. The resulting films were characteriz ed using X-ray diffraction, impedance spectroscopy, and Raman spectroscopy. Because of the different electrode potentials associated with this materia l system, thin films of these materials deposited by spin coating could be suitable as a cathode for Li-ion/polymer thin film batteries.
