Articles and methods involving protective membranes for electrochemical cells are generally provided. In some embodiments, a composite protective layer comprising particles and a polymeric binder may be disposed on an electroactive material. The particles may be reactive with lithium, may capable of intercalating lithium, and/or may comprise intercalated lithium. In some embodiments, the electroactive material may be in the form of a first electroactive layer, and a second electroactive layer may be disposed on the composite protective layer. Certain embodiments relate to activating a composite protective layer by intercalating lithium into particles within the layer and/or by reacting the particles with lithium metal.

Protective membrane for electrochemical cells

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.

Electrode protection using electrolyte-inhibiting ion conductor

Articles and methods including composite layers for protection of electrodes in electrochemical cells are provided. In some embodiments, the composite layers comprise a polymeric material and a plurality of particles.

Ion-conductive composite for electrochemical cells

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 10S/cm.
