Abstract: A film plating machine and electroplating production line are provided. The film plating machine has a plating solution tank, conductive substrate film conveying devices and a power supply. A plating solution and an anode member are provided in the plating solution tank. The conductive substrate film conveying devices are provided at both sides of the plating solution tank and configured to clamp two opposite side edges of a horizontally-placed conductive substrate film and drive the conductive substrate film to horizontally enter and exit the plating solution tank in a first direction. A positive electrode of the power supply is electrically connected with the anode member, and a negative electrode of the power supply is electrically connected with the conductive substrate film through the conductive substrate film conveying devices.

Abstract: Provided are a manufacturing method of a core assembly for battery, a core assembly for battery, and a battery pack including the core assembly. The method includes; providing a jelly-roll including a cylindrical main body and a tab group including tabs stacked in an axial direction of the main body and electrically connected to an axial end of the main body, each tab extending outward in a radial direction of the main body; providing a current collecting member including a current collecting portion; electrically connecting the current collecting portion to at least one of the tabs so that the current collecting portion extends outward in the radial direction; and bending the current collecting portion and at least one part of the tabs inward in the radial direction so that no current collecting portion or tab extends beyond an outer peripheral surface of the main body in the radial direction.

Abstract: Provided are a connection member, a battery and a battery pack. The connection member is used for electrically connecting a plurality of tabs of a current collector and includes a connection plate and at least one protrusion arranged on the connection plate and protruding from one side surface of the connection plate in a thickness direction of the connection plate. At least one end of the at least one protrusion in a length direction of the at least one protrusion is formed as a tip in a plane perpendicular to the thickness direction of the connection plate. The tip is configured to puncture the plurality of tabs in the length direction of the at least one protrusion.

Abstract: The present disclosure discloses a current collector assembly, a battery cell, and a battery pack. The current collector assembly includes a current collector and a conductive connection assembly, the current collector includes a plurality of tabs stacked in a thickness direction of the tab, the conductive connection assembly includes a protection plate and a connection plate, the protection plate is arranged on a side of the plurality of tabs in the thickness direction, the connection plate is arranged on the other side of the plurality of tabs in the thickness direction, a partial region of one of the connection plate and the protection plate is deformed to form a protrusion which, during the forming, pierces through the plurality of tabs to be electrically connected to the plurality of tabs.

Abstract: An anode plate for a film plating machine and a film plating machine are provided. The anode plate is formed by splicing a plurality of anode plate splicing units, and two adjacent anode plate splicing units are separated by an insulating medium. Each anode plate splicing unit is connected with a power supply. The anode plate is applicable to film plating machines of different breadth.

Abstract: The present disclosure relates to a processing apparatus for a secondary battery current collector. The processing apparatus includes: a foil uncoiling roller; a composite current collector uncoiling roller; a welding device; a plurality of driving rollers; and a coiling roller. Both the foil uncoiling roller and the composite current collector uncoiling roller are disposed on a feeding side of the welding device. The welding device is configured to weld foil to a portion of a composite current collector. The plurality of driving rollers is respectively disposed on a feeding side and a discharging side of the welding device, and has an equal line speed. The plurality of driving rollers is configured to drive the overlapped foil and the composite current collector to downstream. The coiling roller is configured to wind up the composite current collector having the foil welded thereon.
