a Chemical structures of PIL30-X. Composition of PIL30-X is the same while three anions with increasing size are chosen for comparison, including BF4−, OTF−, TFSI−. b DFT simulation of the surface electrostatic potential of three anions, where it ranges from 0.1 a.u. (red) to −0.1 a.u. (blue). c Wide-angle X-ray scattering (WAXS) data of PIL30-X. d X-ray photoelectron spectroscopy (XPS) spectra of N 1 s peak for PIL30-X. e Glass transition temperature (Tg) of PIL30-X. f Ionic conductivity of PIL30-X.
