One of the most important challenges in battery research is to achieve safer devices with enhanced electrochemical performance. Including ionic liquids (ILs) in developing polymeric electrolyte systems for batteries is an interesting approach to improve some properties such as flexibility, thermal stability, safety and minimizing electrolyte dripping in the devices. An additional advantage of polymeric electrolytes is the possibility of replacing the separator, which reduces one of the battery components, thereby reducing costs and facilitating its manufacture. In recent years, interest has increased in polymeric electrolytes for lithium-ion batteries (LIBs) applied to solid polymer electrolytes (SPEs), gel polymer electrolytes (GPEs) and composite-polymer electrolytes (CPEs) that use ILs, resulting nowadays as one of the most fascinating topics in energy storage devices.
