As the global demand for energy generation and storage grows, many novel systems are being introduced as potential solutions to the energy problem that are cost-effective, efficient, and above all, safe to use. Particularly in electrochemical systems, such as batteries and supercapacitors, thermally-responsive polymers have been suggested to be used as “smart materials” as a protective measure in case of thermal runaway and overheating. Since aqueous electrolytes are not applicable to most electrochemical systems, most prominently lithium-ion (Li-ion), ionic liquids (IL) will be researched instead, as IL-polymer electrolytes will be easier to adapt Li-ion systems. Additionally, ILs have negligible vapor pressure, are nonflammable, and are thermally and electrochemically stable, making them ideal candidates for improved safety in Li-ion systems. Above all, these systems must demonstrate reversible characteristics such that upon cooling the battery returns to its original performance and conductivity. Many different thermally-responsive polymers will be created and tested in ILs to determine whether a change in conductivity is observed as the temperature of the system changes.
