The invention discloses a secondary top cover for a square battery and the square battery with the secondary top cover, the secondary top cover comprises a top cover and a negative pole connecting piece, the top cover is provided with a negative pole column, the negative pole connecting piece comprises a connecting piece and a first main body part, the connecting piece is suitable for being connected with the lower end of the negative pole column, and the first main body part is suitable for being connected with the lower end of the negative pole column. The first main body part is arranged below the connecting piece, the first main body part comprises a plurality of first pole claws, the plurality of first pole claws are connected with negative tabs at one end of a battery cell, and the distance between two adjacent first pole claws is equal to the distance between two negative tabs connected with the first pole claws. After the secondary top cover provided by the embodiment of the invention is matched on the battery cell, the stability and the safety of the battery cell can be improved, so that the overall structure of the square battery is more stable.
Description
technical field [0001] The invention relates to the technical field of batteries, in particular to a secondary top cover for a prismatic battery and a prismatic battery with the same. Background technique [0002] In the related art, for the existing battery cells with tabs on both sides, the battery is prone to shake after being installed in the casing, which leads to fatigue fracture or loosening of the connecting line between the tabs and the electrode column, which makes the battery The core is also easily broken or damaged due to collision with the shell, with a high failure rate and poor stability. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, an object of the present invention is to propose a secondary top cover for a prismatic battery and a prismatic battery with it, the stability and safety of the battery can be improved after the secondary top cover is fitted ...
