Abstract The influence of the compatibility of plasticizers on the aggregated structure and the ion-conductive behavior of poly(ethylene oxide)/lithium methoxy di (ethyleneoxy) phenylsulfonate (EO2PSLi) complex were studied using two plasticizers with different polarity, γ-butyrolactone (BL) and 2,5-di(methyl diglycol)-1,4;3,6-dianhydrous sorbitol ether (DGS), a novel pincer-like plasticizer synthesized in this paper. The DGS can effectively destroy the PEO crystalline phase in PEO/EO2PSLi complex and increase the amorphous area in which Li+ cations transport, depending on polymeric segmental movement. However, in BL-plasticized PEO/EO2PSLi complex, the highly polar BL hardly disrupts PEO crystals and only forms a BL-rich phase, a kind of liquid electrolyte tunnel in which Li+ mainly transfers.
