In order to improve ionic conductivity of lithium ion conductive polymer at low temperature, novel styrene derivatives (1-4) were synthesized and their ionic conductivities were measured. An ionic conductivity of polymer 1, was above 10-5 S/cm, even at -60°C. Its activation energy below 20°C exhibited 11 kJ/mol. On the other hand, that of poly(ethylene oxide) electrolyte exhibited 105 kJ/mol. The difference of the activation energy implied that lithium ion transfers in polymer electrolytes was promoted by rotation motion of the dimethoxyphenyl side group instead of segmental motion of polymer main chain.
