Membrane-free redox flow battery with polymer electrolytes.

ABSTRACT: Li metal-based nonaqueous batteries are valued for high voltage and energy density, but face challenges like Li instability, volatile electrolytes, and costly ion-exchange membranes. To address these, we develop a membrane-free battery employing an ion-immobilized polymer electrolyte as anolyte and organic solvent as catholyte. Two polymer electrolytes are created for Li negative electrode: solid polymer electrolyte of polyvinylidene fluoride-co-hexafluoropropylene and gel polymer electrolyte with polypropylene carbonate. While the solid-state electrolyte offers an initial approach, it is associated with slower Li⁺ ions diffusion and lower ionic conductivity. The gel polymer electrolyte, specifically developed to overcome these limitations, improves Li⁺ diffusion, mas
