Electrode protection using electrolyte-inhibiting ion conductor

The use of ion-conducting materials to protect electrodes is generally described. The ion-conducting material may be in the form of a layer that is adjacent to a polymeric layer, such as a porous separator, to form a composite. At least a portion of the pores of the polymer layer may be filled or un...

Zusammenfassung:The use of ion-conducting materials to protect electrodes is generally described. The ion-conducting material may be in the form of a layer that is adjacent to a polymeric layer, such as a porous separator, to form a composite. At least a portion of the pores of the polymer layer may be filled or unfilled with the ion-conducting material. In some embodiments, the ion-conducting layer is sufficiently bonded to the polymer layer to prevent delamination of the layers during cycling of an electrochemical cell.
