Outline of Final Research Achievements |
Development of the system which enables TEM observation of electrochemical reaction in real time is purpose of this project. The key technology for this purpose is use of ionic liquid which is not vaporized under vacuum condition because of its extremely low vapor pressure. The TEM holder equiptted with a electrochemical cell having three electrodes and ionic liquid was made. With this cell, electrochemical reduction of metal ions to observe metal deposition by TEM. Electrochemical reduction of ionic liquid containing Li ion induced deposition of Li metal and that could be observed by TEM.
