Abstract

A lithium metal negative electrode for an electrochemical cell for a secondary lithium metal battery includes a polycrystalline metal substrate having a major facing surface with a defined crystallographic texture. An epitaxial lithium metal layer is formed on the major facing surface of the polycrystalline metal substrate. The epitaxial lithium metal layer exhibits a predominant crystal orientation. The predominant crystal orientation of the epitaxial lithium metal layer is derived from the defined crystallographic texture of the major facing surface of the polycrystalline metal substrate.
