Abstract

Abstract: Three types of chloride‐conducting membranes based on polyvinyl chloride, commercial gelatin, and polyvinyldifluoride‐hexafluoropolymer are introduced in this report. The polymers are mixed with chloride‐containing salts, such as tetrabutylammonium chloride, and cast to form membranes. We studied the structural properties, thermal stability, and electrochemical response of the membranes to understand chloride migration and transport. Finally, the membranes are tested in a prototype solid‐state chloride‐ion battery setup. The feasibility of the membranes for their potential use in anion batteries is discussed. Abstract : Keeping anion things : It is demonstrated that chloride‐conducting polymer membranes can be used as solid electrolyte in chloride‐ion batteries.
