| Outline of Final Research Achievements |
We investigated the diffusion behavior of metal ions in ionic liquid close to the electrode under the cathodic potential by using of Eelectrochemical XPS (EC-XPS) and Chronoamperometry, based on our original hopping-like diffusion model. We found a few factors to control the diffusion behavior of metal ions such as hole concentration, structure of ionic liquid molecule, solution temperature and clarified how those factors affect the diffusion behavior. On the other hand, we found that the diffusion path was switched from polar domain to non-polar domain by controlling the hole concentration.
