Mixed anion effect on ion transport and electrochemical properties. (a) MSD profiles obtained from MD simulations for Li+, FSI–, FTFSI–, and PDADMA+ at a PDADMAFSI/LiFTFSI ratio of 1:8 (red lines) and a PDADMAFSI/LiFTFSI/LiFSI ratio of 1:4:4 (blue lines) at 80 °C. (b) Tg and ionic conductivity measured as a function of the FSI mole fraction in mixed LiFTFSI/LiFSI systems with PDADMAFSI at polyIL unit:Li+ of a 1:8 ratio. (c) Experimental self-diffusion coefficients of FTFSI– and Li+ and ionic conductivity at 80 °C. (d) Nyquist plots after the polarization for PDADMAFSI/LiFTFSI at a 1:8 ratio and for PDADMAFSI/LiFTFSI/LiFSI at a 1:4:4 ratio at 80 °C.
