Recently, various studies related to adding functionalities to battery separators have been reported. In particular, high conductivity of separators is considered to be one of the crucial properties for fast charge/discharge characteristics in battery applications. Here, we attached sulfobetaine zwitterionic functional group on polydopamine-coated polyolefin separator to induce dissociation lithium-ion cation and counter anion for high ion conductivity. Furthermore, zwitterion/polydopamine composite-coated separator showed prohibition effect for “polysulfide shuttling” in a lithium-sulfur battery system. |
