AI Technical Summary

Technical Problem

The reliability of existing battery cells needs to be improved, especially in terms of redundancy and cost issues in the connection between the conductive parts and the terminals and in space utilization.

Method used

By placing the second folded portion formed by folding the tabs within the outer contour of the pole post and the orthogonal projection portion of the pole post, and by using an adapter plate to indirectly connect it to the pole post, and by combining a receiving portion and a receiving groove on the pole post, the layout of the conductive part is optimized to reduce redundancy and space occupation.

Benefits of technology

It improves the reliability and stability of individual battery cells, reduces the cost of conductive parts, enhances the reliability and space utilization of electrical connections, and extends the service life of individual battery cells.

Abstract

The application discloses a battery monomer, a battery and an electric device, and belongs to the technical field of batteries. The battery monomer comprises a pole and a battery core assembly. The battery core assembly comprises an active material coating part and a plurality of tab pieces extending from the active material coating part along a first direction. The plurality of tab pieces are gathered to form a first gathering part at one end close to the active material coating part. The plurality of tab pieces are gathered to form a second gathering part at one end away from the active material coating part. The first gathering part connects the second gathering part and the active material coating part. The end part of the second gathering part connected with the first gathering part is at least partially located within the outer contour range of the pole in the orthogonal projection of the pole along the first direction. The battery monomer is beneficial to shorten the length of the conductive part and improve the reliability of the battery monomer.
