Abstract

In order to improve ionic conductivity of lithium ion conductive polymer at low temperature, novel styrene derivatives (1) was synthesized and an ionic conductivity of its homopolymer electrolyte showed a low activation energy. In this improvement of the polymer electrolyte, several polymerization conditions and several kinds of lithium salts are investigated by the robust design. By judging from the conductivities of polymer electrolytes with copolymers with various monomers, the best composition was vinyl acetate 0.3 eq, LiBETI 2.5eq for the monomer with the side group. By comparing with the electrolyte with the homopolymer, their ionic conductivities were enlarged. This result indicates that side group rotation would be promoted by optimizing the distance between the rotating side groups.
