Conductive module, cover plate assembly, and battery cell

A cover plate assembly comprising:

• a cover plate and a conductive module;
• the conductive module including
• a pole that includes a metal post and a metal layer bonded to a surface of the metal post, wherein the metal layer includes a clamping portion, and
• a terminal pressing block being connected to the pole, the terminal pressing block including a through hole, and the terminal pressing block being sleeved on the pole by the through hole, wherein the clamping portion is clamped between the metal post and the terminal pressing block;
• a current collector being located on a side of the cover plate away from the terminal pressing block and welded to the pole, wherein the cover plate comprises:
• a cover plate body,
• a first insulating member disposed between the terminal pressing block and the cover plate body,
• a second insulating member disposed between the cover plate body and the current collector, and
• a sealing member disposed between the cover plate and the pole;
• and
• wherein the pole passes through the cover plate, and the terminal pressing block is located on one side of the cover plate.
