Outline of Final Research Achievements

The electrode-electrolyte interface, which is one of the significant interesting theme of Li-ion battery, was focused in this research. It was studied by environmental atomic force microscopy (AFM) in the non-aqueous condition, and several surface reaction was revealed at the Li4Ti5O12 and LiMn2O4 electrode. These surface phenomenon was also investigated by transmission electron microscopy and discussed based on the crystal structure and chemical composition change. Atomic resolution imaging of electrode surface in the liquid condition is one of the challenging for liquid base AFM technology, as well as the battery research. In this research, we clearly acquired atomic scale image of Li4Ti5O12(111) surface in aqueous liquid condition, and this is a key result to discuss the solid-liquid interface structure for atomic level. Finally, first principle calculation of Li-LiTi2O4(001) surface was performed and Li insertion mechanism was discussed with the charge distribution feature.
