Electrochemistry in Non–aqueous Systems
Double–layer charging in ionic liquids
The electrochemical double-layer in Ionic liquids (i.e., room temperature molten salts) differs significantly from aqueous solutions, as there is no solvent involved. We studied the DL charging and layer formation in IL on Au(111) by EC microcalorimetry and STM tunneling barrier height measurements.
Lithium deposition
We investigated the lithium bulk deposition from a standard battery electrolyte, e.g. a solution of LiPF6 in a 1:1 mixture of ethylene carbonate and dimethyl carbonate by microcalorimetry. From the reaction entropy of the metal bulk deposition we obtained information on the Li solvation and ion pairing in solution.
