Patent attributes
A protective layer system for a metallic lithium-containing anode of a lithium cell, for example a lithium-sulfur cell and/or lithium-oxygen cell. To increase the service life and reliability of the cell, the protective layer system includes a lithium ion-conducting layer, in particular an inorganic layer, on the anode side. The anode-side layer has an anode contact side which rests against or which may be placed against the anode. At least one lithium ion-conducting layer, in particular a polymer layer, which contains at least one agent which is reactable with metallic lithium to form an electrically insulating solid is situated on a side of the anode-side layer opposite from the anode contact side. Moreover, the invention relates to an anode which is equipped with such a protective layer system, a lithium cell, and a lithium battery.
