    摘要: A secondary battery includes an electrode assembly having a relatively large capacity due to reducing a width of an uncoated portion and increasing a width of a coated portion by improving welding strength through a combination of ultrasonic welding and laser welding, and a manufacturing method thereof. The manufacturing method of the secondary battery includes preparing at least one electrode assembly including an uncoated portion, provisionally welding the uncoated portion by ultrasonic welding, coupling a current collector having an elastic property to the provisionally welded uncoated portion, and welding the uncoated portion and the current collector by laser welding.

    摘要: Apparatus and methods to reduce granule disruption during manufacture of electrochemical cells, such as a metal halide electrochemical cell, are provided. In one embodiment, a current collector can include a diffuser strip extending beneath an aperture configured to receive an injection stream of molten electrolyte. The diffuser strip can be configured to dissipate an injection stream of molten electrolyte when the molten electrolyte is injected into an electrochemical cell. In this way, disruption of a granule bed by the injection of the molten electrolyte during manufacture of the electrochemical cell can be reduced.

    摘要: A nonaqueous electrolyte secondary battery includes: a wound electrode body that is formed by laminating an elongated sheet-shaped positive electrode current collector foil, an elongated sheet-shaped negative electrode current collector foil, and an elongated sheet-shaped separator to obtain a laminate and winding the obtained laminate; a nonaqueous electrolytic solution; and a case that accommodates the wound electrode body and the nonaqueous electrolytic solution. A solid electrolyte interface film derived from an oxalato borate complex is formed on at least a surface of the negative electrode active material layer. The positive electrode current collector foil satisfies the following conditions of (a) 700%≦α≦760% and (b) 530%≦β≦590%, where α represents a 60-degree specular gloss in a direction parallel to a longitudinal direction of the positive electrode current collector foil, and β represents a 60-degree specular gloss in a width direction perpendicular to the longitudinal direction of the positive electrode current collector foil.
