||Ionic liquid are researched as potential electrolytes for high performance due to their have unique properties of low vapor pressure, high thermal stability and high electrochemical stability. However, the utilization of ionic liquid for energy storage devices is limited to electrolytes. So we report a new method to wide the application of ionic liquid. Our new method is used ionic liquid as a binder for electrical devices. In the course of synthesis with binder, silanol reaction used as a cross-linked to prevent the binder from dissolving. In this study, our new binder showed thermal stability, mechanical stability and performance improvement better than conventional binder.
