A polycarbonate-based copolymer was developed by copolymerization with poly(decamethylene carbonate) [P(DMC)], pentaerythritol, triethylene glycol (TEG), 3,9-bis(1,1-dimethyl-2-hydroxyethyl)-2,4,8,10-tetraoxaspiro[5.5]undecane (spiroglycol, SPG) and was evaluated as an SPE. By comparing SPEs containing 60 wt % LiTFSI, we find that the copolymerization of SPG significantly improves the mechanical stability of SPE. branch-P(DMC/TEG/SPG) that has been copolymerized with all monomers displayed the best ionic conductivity at room temperature, a value of 7.4 × 10–6 S cm–1 at 30 oC.
