New energy power battery shell material 3003 H14 aluminum coil

New energy power battery shell material 3003 H14 aluminum coil can be integrally stretched and formed

In the manufacture of electric vehicles, the power battery system shell (battery shell) is the carrier of the battery module, which plays a key role in the stable operation and safety protection of the battery module. Its manufacturing materials need to ensure the strength, rigidity and collision safety requirements .

Lightweight is an unavoidable topic for electric vehicles. In addition to the lightweight of the body structure, the battery pack itself also needs to be lightweight. In addition to improving the energy density of the battery and optimizing the design of the battery module, the lightweight of the battery case is also one of the directions of effort.

003 aluminum plate is currently widely used power battery casing material, which belongs to aluminum-manganese alloy, has excellent formability, high corrosion resistance, good weldability and deep drawing performance, and is easy to stretch and form the power battery aluminum casing as a whole.

Power battery shell material 3003 H14 aluminum coil specification range:

Alloy state: H14

Thickness range: 0.8-3.0mm

Width range: 100-2600mm

Aluminum shells are mainly used in prismatic lithium batteries. Compared with steel shells, aluminum shells are lighter and can be made thinner, and the aluminum shell alloy material structure has significant safety performance. The battery aluminum shell made of 3003 H14 aluminum coil has the characteristics of corrosion resistance, impact resistance, good stamping and stretchability, and is not easy to break and leak.

The battery casing must accompany the car for more than ten years, and high-quality casing parts are required, and the selection of raw materials is very important. The chemical composition of battery shell materials and other 3003 aluminum alloys has special requirements when purchasing ingots, and raw material manufacturers need to strictly control them in order to produce raw materials suitable for battery shell materials.
