Outline of Final Research Achievements |
In this study, we tried to form a conductive path in an insulating lithium double oxide particle in order to improve the diffusion reaction of electrons and lithium ions in the lithium double oxide particle. The lithium double oxide particles were prepared by spray pyrolysis process. The conductive path was formed by carbon particles. It was found that changing the starting materials, pyrolysis temperature and frequency of oscillatory wave in spray pyrolysis process influence the microstructure of lithium double oxide particles. It was suggested that changing of the microstructure of lithium double oxide particles are attributable to the thermal behavior of the starting materials and the energy of oscillatory wave.
