AI Technical Summary
Technical Problem
The existing battery tabs are prone to deformation and damage, take up a lot of space, and are not stable, resulting in wasted energy density and unstable connection.
Method used
A support is provided in the recess of the pole post, and the connecting piece is welded to the edge of the recess to form a lug receiving cavity, ensuring the connection strength between the pole post and the connecting piece and the stability of the lug.
Benefits of technology
This prevents the tabs from being squeezed, collided, deformed, or damaged, saves internal battery space, and improves the overall energy density and connection stability of the battery.

Abstract
The utility model provides a battery cover plate structure, which is used in the technical field of batteries, in particular to a battery cover plate, comprising: a pole, one side of the pole facing a pole group is provided with a recess, and the recess is provided with support parts protruding out of the inner side walls on the opposite inner side walls in the first direction respectively; the connecting piece partially or completely covers the opening of the concave part, the two ends, in the first direction, of the connecting piece are in lap joint with the supporting part and are in butt seam welding with the edge of the opening of the concave part, and a tab containing cavity is formed between the concave part and the connecting piece; the connecting piece is provided with at least one tab lap joint edge, and the tabs of the pole group can bypass the tab lap joint edges from the side, facing the pole group, of the connecting piece and extend into the tab containing cavity. According to the battery cover plate, the supporting part is arranged in the concave part of the pole, and the connecting piece and the edge of the concave part are subjected to butt seam welding, so that the connecting strength of the pole and the connecting piece and the stability degree of the tab accommodating cavity are ensured. The utility model also provides a battery comprising the battery cover plate.
