摘要： Provided are negative electrode assemblies containing lithium sulfide anolyte layers, electrochemical cells including these assemblies, and methods of forming thereof. An anolyte layer may be disposed over a metal layer of a current collector and may be used to separate the current collector from the rest of the electrolyte. The metal layer may include copper or any other suitable metal that forms in situ a metal sulfide during fabrication of the electrode assembly. Specifically, a sulfur containing layer, such as a solid electrolyte, is formed on the metal layer. Sulfur from this layer reacts with the metal of the current collector and forms a metal sulfide layer. When lithium is later added to the metal sulfide layer, a lithium sulfide anolyte layer is formed while the metal layer is recovered. Most, if not all operations may, be performed in situ during fabrication of electrochemical cells.
