Abstract

The invention provides a header component of a secondary battery, and the secondary battery. The header component comprises a top plate provided with an electrode outlet; an electrode terminal that comprises a terminal plate positioned on one side of the top plate and covering the electrode outlet; a first fixing piece at least partially encircling the terminal plate, so as to fix the electrode terminal on the first fixing piece; and a second fixing piece comprising a main body and a first connection part connected with the main body and extending towards the direction that is far away from the terminal plate, wherein the main body is joined with the first fixing piece, and the first connection part is joined with the top plate. One or more purposes of simplifying the structure of the topplate component, increasing the stability of connection between the post and the top plate, and enhancing the airtightness of the top plate component can be achieved.

Description

technical field [0001] The invention relates to the technical field of energy storage devices, in particular to a top cover assembly of a secondary battery and the secondary battery. Background technique [0002] New energy vehicles are being widely promoted at home and around the world, but there are still many things to improve in order to completely replace fuel vehicles. For example, the mileage of the car is small, the cost of the battery pack is high, and the reliability of the battery pack needs to be further resolved. Based on the above problems, higher requirements are put forward for the power battery, the core component of electric vehicles, such as higher energy density and lower cost for the power battery. [0003] At present, the power battery generally adopts a square hard shell structure. The power battery shell includes a shell and a top cover assembly. The power battery shell provides a closed space to accommodate the electrode assembly and electrolyte. Th...
