Outline of Final Research Achievements |
In this research, nanoscale electrochemical operand measurement system with Raman spectroscopy was developed. The system is based on a nanopipette used in electrochemical microscopy. The system can measure lithium-ion (de)intercalation process on the electrode of lithium-ion batteries with cyclic voltammogram and Raman spectrum at the same time during the (de) intercalation process as operand measurement. It was demonstrated by on edge/basal plane of HOPG substrate.

Academic Significance and Societal Importance of the Research Achievements |
本計測機構を開発することにより、リチウムイオン電池内で起こるイオンの脱挿入反応を電気化学反応と光学特性(ラマン散乱光)の同時計測が可能となった。また、ナノピペットを用いることにより、通常計測が困難であったナノスケール領域での電極内の反応性の変化を追うことが可能となった。今後は電気化学顕微鏡などの走査機構を持つ計測技術に融合することで、電極内における反応性の分布と構造変化や析出物などの同時計測および可視化が可能となることが期待される。
