Abstract
Provided are materials that may be used in or as a separator in an electrochemical cell such as a lithium sulfur battery. The separator includes a material capable of absorbing and desorbing a polysulfide. The inclusion of the materials in a separator provide for reduced sulfur loss from a cathode during cycling thereby improving cycle life.
