Applications of Ionic Liquids in Electrochemical Energy Conversion and Storage

摘要

Ionic liquids have found widespread applications in electrochemistry, and are increasingly used in the field of electrochemical energy conversion and storage. In battery technology, the use of ionic liquids can increase the device safety significantly and help in enabling alternative technologies like Mg ion batteries. In fuel cell technology, new, water-free proton conducting membranes and new options for synthesis and improvement of catalysts are in the focus of research. In this paper some applications, advantages and drawbacks of ionic liquids in electrochemical energy technology are reviewed. Some examples from the authors' own work in batteries and electrocatalysis using standard electrolytes are presented, and the potential improvements by using ionic liquids in these studies are discussed.
