Based on our previous finding that room temperature ionic liquid (RTIL) can be observed by scanning electron microscopy (SEM) without charging of the liquid, a specifically designed electrochemical cell has been developed to observe electrochemical metal deposition from RTIL in real time by SEM. The cell was fabricated employing a fluorine doped tin oxide transparent glass, whose surface was divided into three electrodes. Then, the effectiveness of the fabricated cell was confirmed by demonstrating silver deposition form RTIL of 1-butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide (BMI-TFSI) containing Ag-TFSI, which gave growth of granular and dendritic forms of Ag deposit.
