Abstract: The solid electrolyte membrane in this application has a first surface and a second surface opposite the first surface, where the first surface is provided with several micropores that extend into an interior of the solid electrolyte membrane without penetrating to the second surface. This application further provides a solid-state lithium metal battery, battery module, battery pack, and apparatus containing such solid electrolyte membrane. In the solid electrolyte membrane provided in this application, the micropores provided on the first surface of the solid electrolyte membrane do not penetrate to the opposite second surface, so that lithium ions can be induced to deposit in the micropores. This reduces the risk of lithium dendrites growing or even penetrating through the solid electrolyte membrane due to non-uniform deposition of lithium ions at other locations, thereby preventing short circuit of a solid-state lithium metal battery.
