Embodiment Construction

[0040] refer to Figure 1 to Figure 5 , while the present invention provides in a specific embodiment, a kind of energy supply lithium battery pack, comprises electric core 1, battery pack case 3 and separator 2, wherein separator 2 is made of foam body 21 and metal skeleton 22 composite.

[0041] The shell 3 is preferably an aluminum alloy shell.

[0042] In one example, the foam 21 may have a desirable thermal stability, flexibility, and explosion-proof properties. In addition, the main surface layers on both sides of the foam may include a fabric support such as non-woven fabric, glass fiber cloth, and the like. Specifically, the fabric support is disposed on the foam to enhance its strength, impact resistance, and formability.

[0043] It also includes an alloy skeleton 22. The alloy skeleton is a metal stamping part. An alloy flat plate, especially a flat plate with good stamping performance, is used to form protrusions protruding to both sides through stamping. The pr...

Abstract

The invention discloses a lithium battery separator and a lithium battery pack, wherein the lithium battery separator includes a foam body and a skeleton, the skeleton is a metal stamping part, and is formed on both sides by stamping on the skeleton Evenly arranged Z-shaped bending, the end of the Z-shaped bending is a planar support point for matching with the battery; the foam is compounded on the skeleton and the main surfaces on both sides of the foam are located at the Z inside of the bend. The separator combines the dual advantages of inorganic foam and metal plate. The metal plate has the functions of impact resistance, elasticity and support. The inorganic foam has the performance requirements of anti-explosion and has a wide application space.

Description

technical field [0001] The invention relates to the technical field of cell separators, specifically lithium cell separators and battery packs. Background technique [0002] Due to uncertainty about oil prices and growing concerns about the environmental impact of hydrocarbon fuels, there is great interest in changing the use of energy and using alternative energy sources. This concern has a particular impact on automobiles, which typically use a considerable amount of petroleum-derived hydrocarbon fuels and can produce various pollutants. As such, the automotive industry has been seeking to develop hybrid and electric vehicles. [0003] Both hybrid and electric vehicles utilize electrical storage, often batteries and other chemical-based electrical storage systems. For example, in a hybrid vehicle, the battery discharges when the vehicle is being used, but it can also be recharged during braking by energy recovery or by a generator driven by a small internal combustion en...
