摘要： Described herein are current collectors comprising metal grids as well as electrodes and lithium-metal cells comprising such current collectors and methods of fabricating such current collectors, electrodes, and lithium-metal cells. A thin current collector comprises a polymer base and a metal layer positioned on, directly interfaces, and supported by one side of the polymer base. A thin current collector also comprises a metal grid, which directly interfaces and is supported by the edge of the polymer base. The metal grid is electrically coupled to the metal layer, e.g., by overlapping or at least forming an interface with the metal layer. In an electrode that further comprises an active material layer supported on the metal layer, the metal grid extends away from the active material layer. In an electrochemical cell, the metal grid can be connected to the metal grids of other electrodes and/or cell tabs.

摘要： A sealing body for sealing an upper opening of a battery can having a tube shape with a closed bottom includes an electrode terminal, a sealing plate, and gaskets. The electrode terminal includes a flat plate-shaped stepped portion in an area of a lower surface of a flat plate-shaped terminal portion. The electrode terminal has an inserting portion extending downward in a columnar shape on a lower surface of the stepped portion, and a protrusion in a non-circular planar shape that goes around the inserting portion. The sealing plate has an opening, and has an upper surface and a lower surface on which a non-circular sealing-plate recessed portion and a sealing-plate protruding portion are formed. The gaskets have a shaft portion inserted through the opening of the sealing plate, and a protruding portion that engages the sealing-plate recessed portion and a recessed portion that engages the sealing-plate protruding portion.

摘要： The number of steps is reduced in the formation process of an electrode. Deterioration of the electrode is suppressed. A highly reliable lithium secondary battery is provided by suppressing the deterioration of the electrode. A method for forming a negative electrode and a method for manufacturing a lithium secondary battery including the negative electrode are provided. In the method for forming the negative electrode, graphene oxide, a plurality of particulate negative electrode active materials, and a precursor of polyimide are mixed to form slurry; the slurry is applied over a negative electrode current collector; and the slurry applied over the negative electrode current collector is heated at a temperature higher than or equal to 200° C. and lower than or equal to 400° C. so that the precursor of the polyimide is imidized. The graphene oxide is reduced in heating the slurry to imidize the precursor of the polyimide.
