Abstract

Spinel lithium manganese oxide thin films were prepared on a stainless steel substrate by a spray pyrolysis method using a precursor solution of lithium acetate and manganese acetate in 1:1 (v/v) mixture of methanol and distilled water. Thermal analysis of the precursor solution was carried out for determining the required temperature for the phase formation or complete crystallization of the precursor sample. The as-deposited thin films were calcined at different temperatures from 500 to 700 °C to find out the degree of crystallization of LiMn2O4 thin film. The structural property of the prepared thin film was analyzed by X-ray diffraction. The morphology and the grain size of the deposited film were evaluated by scanning electron microscopy. The electrochemical behaviour of the prepared LiMn2O4 thin films was analysed by cyclic voltammetry and charge–discharge studies. The results showed that the prepared LiMn2O4 thin films had good electrochemical properties.
