AI Technical Summary

Technical Problem

Existing batteries are prone to problems such as bending deformation, wrinkling, deformation, delamination, and breakage when the electrode assembly is too long or too wide, and it is difficult to install into the casing, resulting in reduced yield and damage to the electrode assembly.

Method used

The electrode assembly is divided into multiple electrode components, and the first and second partitions separate the accommodating space on both sides of the thickness direction of the layer plate. A support frame is set to support the electrode components and avoid direct contact with the shell. The support frame is used to contact the shell to prevent damage when the electrode assembly is inserted into the shell.

Benefits of technology

It effectively avoids bending and deformation of the electrode assembly, improves the structural strength of the battery, prevents damage to the electrode sheets, increases battery capacity and voltage, and extends the service life and range of the electrical device.

Abstract

The utility model relates to the technical field of batteries, in particular to a battery and an electric device. The battery comprises a shell, a pole group, a supporting frame and a partition plate support, the pole group comprises a plurality of pole group split bodies, the partition plate support is arranged in the supporting frame, the partition plate support comprises a layer plate, at least one first partition plate and at least one second partition plate, and the first partition plate and the second partition plate are arranged in a crossed mode and protrude out of the two side faces of the layer plate in the thickness direction respectively. The at least one first partition plate is arranged at intervals in the first direction, the at least one second partition plate is arranged at intervals in the second direction, so that the two side faces, in the thickness direction, of the layer plate are divided into a plurality of containing spaces arranged in an array mode, each containing space is provided with a pole group split body, the supporting frame is arranged in the shell, the size of the single pole group split body can be shortened, and the size of the pole group split body can be reduced. The split deformation of the pole group is avoided, and the capacity and voltage of the battery are improved; and the pole group can be prevented from being in direct contact with the shell when entering the shell, so that the pole group is prevented from being damaged.
