Inion Sulfocation Membranes Plasticized with Propylene Carbonate

The rapidly developing field of portable energy sources requires the search and development of effective materials for such devices. To improve the safety of the most common metal-ion batteries (lithium- and sodium-ion), instead of a liquid electrolyte, it is proposed to use a gel-polymer electrolyte with unipolar conductivity based on a Nafion-like electrolyte (Inion), plasticized with aprotic solvents. The work presents the results of a study of the thermal stability, molecular structure and supramolecular packing, as well as ionic conductivity of the Inion membrane in lithium and sodium forms, plasticized with propylene carbonate, using methods of simultaneous thermal analysis, IR spectroscopy, small-angle X-ray scattering and impedance spectroscopy.
