Optimizing the Electrochemical Performance of Imidazolium-Based Polymeric Ionic Liquids by Varying Tethering Groups

摘要: Due to the drawbacks of conventional organic liquid electrolytes, such as leakage, volatility, flammability, and toxicity, synthesis solvent-free electrolyte materials has been studied world-wide in order develop highefficient low-cost electrochemical devices with sufficient long-term stability. Among novel solid-state polymer particular, ionic liquids (ILs) poly(ionic liquid)s (PILs), offering low vapor pressure, non-flammability, high conductivity, a window, stability, represent an important class for applications. An property that defines ion conductivity ILs is glass transition temperature (Tg) Tg IL expected have higher mobility, which translates conductivity.
