Outline of Final Research Achievements

The electrochemical reaction for battery is elucidated from the spectroscopic viewpoint. The battery quality depends on the solvation or desolvation of activated ion at the high energy interface between electrodes and electrolytes. However, the details about the electrochemical reaction have not been clarified yet. In this study, the vibrational spectroscopic technique of the Raman spectroscopy has been carried out for the battery active materials. Obtained results give big knowledge to the development of the battery industry which needs rapid charging and discharging of lithium ion battery for electric vehicle.
