In a method of manufacturing an electrochemical cell, a porous or non-porous electrically conductive metal substrate may be provided. A conformal metal chalcogenide layer may be formed on a surface of the metal substrate. The metal substrate with the conformal metal chalcogenide layer may be immersed in a nonaqueous liquid electrolyte solution comprising a lithium salt dissolved in a polar aprotic organic solvent. An electrical potential may be established between the metal substrate and a counter electrode immersed in the nonaqueous liquid electrolyte solution such that lithium ions in the electrolyte solution are reduced to metallic lithium and deposited on the surface of the metal substrate over the metal chalcogenide layer to form a conformal lithium metal layer on the surface of the metal substrate over the metal chalcogenide layer.
