The invention belongs to the technical field of battery manufacturing, and discloses a battery top cover and a battery, and the battery top cover comprises a top cover body, a conductive assembly, a sealing element and a sealing ring. A mounting hole is formed in the top cover body, the conductive assembly comprises a pole, the pole penetrates through the mounting hole, a liquid injection hole is formed in the pole, the liquid injection hole penetrates through the two ends of the pole, the sealing element can block the liquid injection hole, the length of the sealing element in the first direction is smaller than that of the pole in the first direction, and the first direction is parallel to the axial direction of the liquid injection hole. And the sealing ring is sleeved outside the pole and is used for sealing the gap between the pole and the mounting hole. And after liquid injection is finished, the liquid injection hole is blocked by a sealing element, and the length of the sealing ...
