摘要:
A lithium-secondary-battery negative electrode having a protective layer to prevent the surface deterioration of the inorganic solid electrolytic layer. The negative electrode comprises metallic lithium or a lithium-containing metal, a first inorganic solid electrolytic layer (thickness: a) formed on the metal, and a second inorganic solid electrolytic layer (thickness: b) formed on the first inorganic solid electrolytic layer. The thickness ratio b/a is specified to be more than 0.5.
