摘要： A three-dimensional composite metallic lithium negative electrode, a metallic lithium battery and an apparatus are disclosed. The composite metallic lithium negative electrode includes metallic lithium particles and a three-dimensional polymer framework, where the metallic lithium particles are filled in the three-dimensional polymer framework, and the three-dimensional polymer framework includes lithium-philic a fragments, active sites and polymer-containing moieties. The present application improves a volume effect of the metallic lithium negative electrode in charge and discharge process, which can inhibit side reactions of metallic lithium and electrolyte; increase a specific surface area of the metallic lithium negative electrode, and introduce lithium-philic nano-sites, thereby can guide a uniform deposition of the metallic lithium and effectively inhibit generation of lithium dendrites. In addition, the three-dimensional framework coated with active lithium can effectively reduce risks of brittle SEI film faced by traditional solutions.

摘要： 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.

摘要： A solar cell includes a plurality of sub-cells. The plurality of sub-cells are disposed sequentially along a first direction. The plurality of sub-cells each include a first photovoltaic conversion layer for performing photovoltaic conversion. The first direction is perpendicular to a thickness direction of the sub-cells. Along the first direction, a trend of change in a thickness of the first photovoltaic conversion layer of each sub-cell is negatively correlated to a trend of change in a cross-sectional area, perpendicular to the thickness direction, of each first photovoltaic conversion layer, so as to improve uniformity of photocurrents output by the sub-cells and uniformity of electrical current.
