1. An electrochemical cell comprising:

  • (a) a cathode comprising an electroactive sulftur-containing material;

    (b) an anode; and

    (c) a non-aqueous electrolyte interposed between said anode and said cathode, wherein said anode comprises;

    (i) a first anode active layer comprising lithium metal;

    (ii) a multi-layer structure in contact with a surface layer of said first anode active layer, wherein said multi-layer structure comprises three or more layers, wherein at least one of said three or more layers comprises a non-electronically conductive single ion conducting layer and at least another one of said three or more layers comprises a polymer layer; and

    wherein said first anode active layer further comprises an intermediate layer selected from the group consisting of temporary protective metal layers and plasma CO2 treatment layers, wherein said intermediate layer is interposed between said first anode active layer and said multi-layered structure.
