The Handbook of Ionic Liquids: Electrochemistry, a title in the Handbook of Ionic Liquids series, offers a comprehensive review of the electrochemical properties and applications of ionic liquids. The opening chapters provide an introduction to the chemical and historical background of ionic liquids, plus a thorough description of their electrochemical and transport properties. Subsequent chapters build on this foundation to cover more advanced topics such as reference electrodes, electrochemical reactions in ionic liquid solvents, electropolymerization, and electrowinning. The final chapter discusses the many electrochemical applications of ionic liquids, including lithium batteries, double layer capacitors, actuators, and photoelectrochemical solar cells.
