Abstract

The present disclosure provides a connection structure, a cover assembly and a battery. The connection structure includes a tab connection portion and a pole connection portion that are arranged at an angle to each other. The tab connection portion is configured to connect with a tab of the core pack. The pole connection portion is configured to connect a pole. A thickness of the tab connection portion is greater than a thickness of the pole connection portion, so that a distance from the tab welded to the tab connection portion to a side surface of the core pack is greater than the thickness of the pole connection portion. In the present disclosure, the thickness of the pole connection portion is less than that of the tab connection portion, so that the distance between the welding position of the tab connection portion and the core pack can be increased, thereby reducing the heat transfer speed. The reduced thickness of the pole connection portion can reduce the space occupied by the tab connection portion in the housing, thereby improving the space utilization rate of the battery and increasing the battery capacity.
