Ionic liquids: as a solvent for electrodeposition of metals and energy conversions

Gengan Saravanan, T. R. Heera


Over the past decade, Ionic Liquids have attracted much interest for their use as non-aqueous electrolytes in electrochemical applications. In this context, their conductivity as well as their electrochemical stability are the most important physical properties. Together with other interesting properties such as their negligible vapor pressure and their non-flammability, they appear to be ideal electrolytes for many interesting applications such as electrodeposition of metals with maximum current efficiency (CE) because of no H2 evolution. This review covers the newest aspects of ionic liquids in applications where their ion conductivity is exploited; as electrochemical solvents for metal electrodeposition, and as batteries and fuel cells where conventional media, organic solvents in batteries and supercapacitors.

Keywords: electrochemical applications, electrodeposition, ionic liquids
