Abstract: Provided are a current collector assembly, a battery cell, and a battery pack. The current collector assembly includes a plurality of layers of tabs, a protection plate, a connection plate, and at least one protrusion. The plurality of layers of tabs is stacked in a thickness direction of each of the tabs. The protection plate is arranged at a side of the plurality of layers of tabs in the thickness direction of each of the tabs. The connection plate is arranged at another side of the plurality of layers of tabs in the thickness direction of each of the tabs. The at least one protrusion is arrange between the connection plate and the protection plate. Each of the at least one protrusion penetrates the plurality of layer of tabs, and is connected to the plurality of layers of tab.

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: A battery having a housing, a core assembly, a separator and a top cover assembly is provided. The housing defines an accommodating cavity for receiving the core assembly. The core assembly has a jelly-roll having a body portion, and an insulating sheet. The body portion has a top end surface and a bottom end surface located at the ends of the body portion respectively, and a peripheral surface connected to the top the bottom end surfaces. The insulating sheet covers the peripheral surface and/or the bottom end surface. The separator is in the housing and separates the bottom end surface of the jelly-roll from a bottom surface of the housing. The top cover assembly is connected to the housing in a sealed manner and configured to close the opening of the housing. The top cover assembly is spaced from the insulating sheet.
