Abstract
An example of a flexible membrane includes a porous membrane and a solid electrolyte coating formed on at least a portion of a surface of the porous membrane, in pores of the porous membrane, or both on the surface and in the pores. The solid electrolyte coating includes i) a polymer chain or ii) an inorganic ionically conductive material. The polymer chain or the inorganic material includes a group to interact or react with a polysulfide through covalent bonding or supramolecular interaction.
