Provided is an anode for use in electrochemical cells, wherein the anode
active layer has a first layer comprising lithium metal and a multi-layer
structure comprising single ion conducting layers and polymer layers in
contact with the first layer comprising lithium metal or in contact with
an intermediate protective layer, such as a temporary protective metal
layer, on the surface of the lithium-containing first layer. Another
aspect of the invention provides an anode active layer formed by the
in-situ deposition of lithium vapor and a reactive gas. The anodes of the
current invention are particularly useful in electrochemical cells
comprising sulfur-containing cathode active materials, such as elemental
sulfur.
