a Phase separation of DMA-DEE systems with different amounts of LiTFSI and LiNO3. The color is from the pigment dissolved in them. b Snapshot of the MD simulation of No. 2 system showing apparent phase separation behavior. c Calculated MSD of Li+ in the three biphasic systems (No. 2, No. 3, No. 7) as a function of the simulation time. The diffusion coefficient of Li+ was deduced by fitting. d Li+ conductivity of the top and bottom phases in No. 2, No. 3, and No. 7 biphasic systems. e Proportions of DEE, DMA, LiNO3 and LiTFSI in the top and bottom phases of the No. 2 biphasic system.
