AI Technical Summary

Technical Problem

In the existing technology, the connection requirements of the battery tabs, connecting plates, and terminals occupy a large amount of space inside the battery casing, resulting in a low battery energy density.

Method used

A groove is set on the pole post, and the pole post and the connecting plate cooperate to form a tab connection cavity. The second distance between the connecting plate and the side wall of the groove is defined, so that the tab can extend into the tab connection cavity and connect with the plate surface of the connecting plate away from the pole group, avoiding additional space occupation.

Benefits of technology

It improves the space utilization inside the battery casing and enhances the energy density of the battery.

Abstract

The application provides a battery cover plate and a battery, and relates to the technical field of batteries, wherein the battery cover plate comprises a body, a pole and a connecting plate, the pole is arranged on the body, and the pole is provided with a groove on the side facing the pole group; the connecting plate is connected with the pole; the connecting plate and the bottom wall of the groove have a first spacing to cooperate with the inner wall of the groove to form a tab connecting cavity; the connecting plate and at least one side wall of the groove have a second spacing to form an opening communicating with the tab connecting cavity, and the ratio of the second spacing to the thickness of the tab is in the range of 1.2-10; in the setting mode, the tab is connected with the connecting plate in the tab connecting cavity, that is, the tab is connected with the connecting plate in the height space of the pole, so that the space for connecting the tab and the connecting plate between the pole and the pole group is no longer reserved, and the space utilization rate inside the battery shell can be improved, and the battery has a higher energy density.
