Outline of Final Research Achievements

We have studied aiming to clarify the correlation between lattice size change and activation energy of charge transfer process by hybridizing expandable piezoelectric element by voltage application with lithium battery material epitaxial thin film.
111 - oriented LiMn2O4 epitaxial thin film was fabricated on LiNbO3(LNO) substrate and mica substrates and piezoelectric properties by sol-gel method. The electrochemical characteristics of the obtained thin film were evaluated, and it was confirmed that charge - discharge performance was confirmed with the film on LNO substrate. The activation energy of the charge transfer resistance decreased by applying voltage to the piezoelectric substrate. These results suggeststhat the activation energy is lowered due to the distortion generated in the film with the expansion of the substrate.
