    摘要： This application provides a battery cover and a battery. The battery cover includes a cover body and a first sealing structure. The cover body is provided with an electrolyte filling port that runs through the cover body, and an electrolyte is injected into the battery through the electrolyte filling port. The first sealing structure includes a sealing nail and a bone nail. The sealing nail is sleeved on at least a part of the bone nail, the sealing nail and the bone nail are inserted into the electrolyte filling port, and the sealing nail and the electrolyte filling port form a first sealing layer through interference fitting, to seal the electrolyte filling port. An outer peripheral wall of the bone nail is provided with a convex part, and a part of the sealing nail is located between the convex part and an inner wall of the electrolyte filling port in a radial direction of the electrolyte filling port. Disposing the convex part can enhance connection stability between the sealing nail and the bone nail, increase a local compression amount of the sealing nail, improve sealing effect, and ensure normal operation of the battery.
