  • Publication number: 20230282808
    Abstract: A method for forming a protective electrode coating on an electrode to be used in a lithium-sulfur battery is provided. The method includes contacting one or more surfaces of the electrode with a polymeric admixture, and polymerizing the polymeric admixture to form the protective electrode coating. The polymeric admixture includes a plurality of monomers, for example heterocyclic acetal monomers and/or cyclic ether monomers, and a lithium difluoro(oxalato)borate (LiDFOB) initiator. In certain instances, the polymeric admixture may also include a structural additive and/or a lithium salt. The contacting may include applying a thin film on the one or more surfaces of the electrode, and the polymerization may be heat activated.
