Solid Polymer Electrolytes Based on Reactive Copolymers of Glycidyl Methacrylate with 2-Hydroxyethyl Methacrylate

Issues related to the use of 2-hydroxyethyl methacrylate–glycidyl methacrylate copolymers as a polymer matrix for developing solid polymer electrolytes are considered. Effect of the composition of copolymers with varying ratio of oxygen atoms in hydroxyl, carbonyl, ether, and epoxy groups and the amount of the added lithium salt on the ionic conductivity of the solid polymer electrolytes is studied. The resulting polymer films exhibit a high ionic conductivity reaching up to 1.2 × 10‒4 to 1.2 × 10‒3 S/cm at 25 and 80°С, respectively.
