Battery shell for achieving radiating and safety of lithium core

Abstract

The invention discloses a battery shell for achieving radiating and safety of a lithium core. The battery shell comprises a shell body, and an opening for containing a battery is reserved in the shell body; a plurality of rings of first radiating protruding edges are arranged on the lateral face of the shell body, and the first radiating protruding edges are parallel; a second radiating protruding edge is arranged on the lateral face of the shell body in parallel in the direction perpendicular to the first radiating protruding edges; a plurality of grooves are formed in the corresponding positions of the first radiating protruding edges; the grooves at the corresponding positions of the first radiating protruding edges jointly form a first radiating channel. The battery shell for achieving radiating and safety of the lithium core has the advantages that the battery shell is in strip protrusion design, an installation person can conveniently carry, take and place the battery shell, and potential safety hazards caused by falling and the like in the battery carrying, taking or placing process are better avoided.

Description

technical field [0001] The invention relates to a battery case, in particular to a battery case for solving the heat dissipation and safety of lithium batteries. Background technique [0002] With the development and application of electric vehicles and energy storage systems at home and abroad, the demand for power batteries as power sources and energy storage carriers is increasing, followed by battery explosions, battery combustion and other incidents. Among them, the heat dissipation design and safety design of the battery case are the main factors affecting the safety of the battery. Therefore, more and more attention is paid to the design of the battery case. For the design of the battery case, according to the case material, it can be divided into steel case, aluminum case, aluminum-plastic film and plastic case and other packaging. Among them, steel shell and aluminum shell packaging have good thermal conductivity, but they have disadvantages such as high productio...

AI Technical Summary

Problems solved by technology

However, there are deficiencies in the design of heat dissipation and safety (such as figure 1 , figure 2 As shown), the heat dissipation channel is single, which is not conducive to heat dissipation after the battery stack is formed, and it is easy to slip during handling, taking and placing, and there are potential safety hazards such as easy damage to people or property

[0005] 1. The heat dissipation specific surface area of ​​the battery case is small, which is not conducive to heat dissipation

[0006] 2. After the batteries are grouped, the batteries and the battery modules are in close contact, and the heat dissipation channels are few and single, which affects the battery cycle life and safety performance

[0007] 3. For the heavy battery module, because the battery case has no anti-slip design, it is not conducive to the installation personnel to carry, pick and place, and it is easy to slip and fall, causing safety hazards to people and property.

[0008] 4. The battery shell has no stripe design, and the shock resistance and mechanical strength are poor

[0009] 5. The design of the battery shell is too thick, and it is easy to form an instant explosion when encountering battery flatulence, and the safety is not high
