Abstract

A novel fabrication technique has been used to prepare nano-structured LiMn2O4 thin films using electrostatic spray deposition (ESD) from suspensions containing LiMn2O4 fine particles. It is found that a mixture of acetylacetone and ethanol in a ratio of 1:1 by volume is a suitable suspension medium to disperse LiMn2O4 fine particles effectively and form colloidally stable suspension. The effects of the processing parameters, such as applied voltages, suspension flow rates and deposition times, on the surface morphology and microstructure of the thin films are examined with scanning electron microscopy (SEM). The results show that the deposited LiMn2O4 thin films are uniform, dense and well adhered to the substrates. Analysis of the crystal structure of the thin films using X-ray diffraction (XRD) indicates the deposited material as being spinel LiMn2O4, which is in fair agreement with the original fine particles.
