Embodiment Construction

[0043] like Figure 1 to Figure 7 , the present invention provides in a specific embodiment, a kind of energy supply lithium battery pack, comprises electric core 1, battery pack housing 3 and separator 2, wherein separator 2 is made of foam 21 and metal framework 22 Composite.

[0044] The shell 3 is preferably an aluminum alloy shell.

[0045] 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.

[0046] 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 by stamping. The protrusions are Z-...

Abstract

The invention discloses a lithium battery core partition plate and a manufacturing method thereof. The lithium battery core partition plate comprises a foaming body and a framework. The framework is a metal stamping part, evenly-arranged Z-shaped bends are formed towards the two sides of the framework in a stamping mode, and the ends of the Z-shaped bends are planer supporting points used for being matched with battery cores. The foaming body is attached to the framework, and the main surfaces of the two sides of the foaming body are located in the Z-shaped bends. The foaming body is a foaming plate formed by ordinary Portland cement, iron aluminate cement, glass beads, mountain flour, hydrogen peroxide, a water reducing agent, water and rubber powder according to the standard through a foaming process, wherein the foaming plate has a certain thickness. A fabric supporting layer is arranged on main surface layers on the two sides of the foaming body. A coating layer is sprayed on the surface of the foaming body. The partition plate integrates the advantages of the inorganic foaming body and the advantages of a metal plate, the metal plate has impact resistance, elasticity and a supporting effect, the inorganic foaming body has the antiknock property, and the partition plate has wide use 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...
