Abstract

Composite structures including an ion-conducting material and a polymeric material (e.g., a separator) to protect electrodes are generally described. The ion-conducting material may be in the form of a layer that is bonded to a polymeric separator. The ion-conducting material may comprise a lithium oxysulfide having a lithium-ion conductivity of at least at least 10−6 S/cm.
