  • Patent number: 11189840
    Abstract: A method for manufacturing a composite electrode for a metal-air electrochemical cell with a liquid electrolyte of basic pH. A liquid solution comprising a fluoropolymer suspended in a solvent is synthesized, then deposited on the outer surface of a porous structure forming an air electrode. The fluoropolymer comprises SO2N groups suitable for conducting hydroxyl ions and is capable of forming a membrane impermeable to at least the liquid electrolyte of basic pH. When the liquid solution is applied to the porous structure, the solvent flows through the porous structure and the fluoropolymer is deposited by aggregating into a layer on the outer surface of the porous structure.
