Abstract
Articles and methods including separators that can be used in electrochemical cells are provided. In some embodiments, a separator comprises at least one separator backbone (as component a)) and at least one polymer (as component b)). The polymer according to component b) may comprises polymerized units of at least one ethylenically unsaturated monomer having no additional functional groups and at least one ethylenically unsaturated anionic monomer. Processes for preparing the separators and the use of said separators in, for example, an electrochemical cell and, in particular, in a battery, are also provided. Electrochemical cells (e.g., a battery) containing a separator are also provided. In some embodiments, lithium-sulfur batteries that include a separator comprising charged groups (e.g., carboxylate groups) are provided.
