Thermal and dielectric studies of polymer electrolyte based on P(ECH-EO)

▶ Thermal and dielectric property of P(ECH-EO):LiClO4 has been studied. ▶ The glass transition temperature of P(ECH-EO) increases with addition of LiClO4. ▶ The maximum ionic conductivity was 1.3 × 10−5 S cm−1 for 15 mol% LiClO4 at 303 K. ▶ The dielectric constant of polymer electrolyte increased with addition of LiClO4.
