Design, Synthesis, and Electrochemistry of Room-Temperature Ionic Liquids Functionalized with Propylene Carbonate

摘要

Alkyl carbonates are often employed as solvents for the study of energy-storage devices (ESD), such as lithium secondary batteries (LSB) and electric double-layer capacitors. Some of these solvents, including propylene carbonate (PC) and diethyl carbonate, have already been put to practical use in modern electronics technology, such as in mobile phones and laptop computers. However, all of these organic solvents have potential safety drawbacks related to their flammable and volatile nature that can lead to explosions and/or fire accidents. Furthermore, lithium anodes with a high theoretical discharge capacity (3860 mAhg~(-1)) cannot be utilized in such solvents owing to dendritic lithium deposition during the charging cycle.
