Solid polymer electrolytes are solutions of salts in the macromolecular polymeric compound. Excellent process ability, flexibility, non-flammability and non-reactivity make them ideal materials for electrochemical devices. The problem in their use is limited conductivity. It increases with increasing salt concentration in the polymer, but at the same time the condition is to increase the glass transition temperature of the polymer and the deterioration of mechanical properties. The use of ionic liquids as additives in polymer electrolytes solved many problems. The mechanical properties of such systems do not deteriorate, and the conductivity may be relatively high. Polymer electrolytes with ionic liquids typically have higher conductivity than the solid polymer electrolytes, sometimes even better than the conductivity of the ionic liquid itself. They also show good mechanical properties, are non-flammable, and remain stable at high temperatures.
