Abstract

Abstract: As the novel polymer electrolyte membrane, crosslinked P(AN-MA-IALi) was synthesized with monormers such as acrylonictrile(AN), methyl acrylate(MA) and itaconic acid lithium(IALi) via solution co-polymerization method. The molecular structure was characterized by means of FTIR, DSC and SEM. The electrochemical performance of polymer electrolyte membrane was studied by AC impedance. The results show that the conductivity of crosslinked P(AN-MA-IALi) based gel polymer electrolyte membrane could get to 10^-5—10^-4 S/cm measured at room temperature. The highest conductivity was 1.89×10^-4 S/cm when the mass fraction of IALi was 3%.

Key words: Gel polymer electrolyte, Poly(AN-MA-IALi), Solution co-polymerization, Ionic conductivity, Lithium ion battery
