Abstract
A buffered negative electrode-electrolyte assembly includes: a porous negative electrode comprising a metal, a transition metal nitride, or a combination thereof; a solid-state electrolyte; and a buffer layer between the porous negative electrode and the solid-state electrolyte. The buffer layer comprising a buffer composition according to Formula (1) MmNnZzHhXx. The buffer composition has an electronic conductivity that is less than or equal to 1×10−2 times an electronic conductivity of the solid-state electrolyte, and the buffer composition has an ionic conductivity less than or equal to 1×10−6 times an ionic conductivity of the solid-state electrolyte.
