| Outline of Final Research Achievements |
In order to fill the gap between the theoretical and the actual capacity of the storage battery, it is necessary to visualize the reactivity on battery material surface as an electrochemical operando imaging. To visualize inhomogeneous reactivity on battery material, we have developed scanning electrochemistry cell microscope (SECCM). SECCM uses electrolyte solution filled nanopipette to form a nanoscale electrochemical cell between nanopipette and sample to characterize the local electrochemical reactivity. In this work, we improved the SECCM software for CV imaging or charge/discharge imaging, established controlled SECCM which place in grove box for evaluating the negative electrode material, and elucidated the metal oxide modification effect of the cathode material surface.
