What are the characteristics of the new energy （EV）battery shell aluminum?

New energy battery shell aluminum and aluminum materials have become the 'new darling' of the automotive industry in recent years due to their lighter weight and good performance. With the outbreak of the new energy vehicle market, all-aluminum bodies, aluminum alloy battery packs, and other aspects have also ushered in a climax of development and application.

Lightweight and high safety make aluminum alloy battery pack casings the mainstream of power battery casings. The power battery shell is made of aluminum material, which is easy to process and form and has good high-temperature corrosion resistance, good heat transfer, and electrical conductivity. Therefore, the battery case using aluminum alloy under the same capacity is thinner than the steel case, and the relative weight is lighter. In addition, once the battery explodes, the aluminum shell of the lithium battery is weaker than the steel shell, and the harm caused by the aluminum shell power battery is relatively lower. So what are the characteristics of the aluminum material of the new energy battery shell that make it so popular?

The battery aluminum shell has a high specific strength, specific modulus, fracture toughness, fatigue strength, and corrosion resistance stability. Because aluminum alloy material has the characteristics of low density, non-magnetic, stable alloy phase at low temperature, small specific resistance in a magnetic field, good air tightness, and fast decay of induced radiation energy. It is widely used in aviation, aerospace, high-speed trains, and machinery manufacturing. It has been widely used in ships, automobiles, and chemical industries.

The surface treatment of the battery aluminum shell is mainly electrostatic spraying, and its color is also very rich. Our factory can make?beige, dark gray, black, military green, etc.

The battery aluminum casing has the advantages of aluminum alloy, so it is also light and durable when it is formed.

The plasticity of the battery aluminum shell is stronger and the productivity is better than other profiles. It also has good castability, so it has good advantages for production.

The battery aluminum case will be treated by two processes, hot and cold so that the battery aluminum case will have strong corrosion resistance. As a result, the battery safety of the aluminum case is better.

This shell also has good ductility and can be made of light alloys with many metal elements, and the material is of high quality. Its chemical properties are stable, non-magnetic, and can be recycled and reused. It is a virtuous and recyclable metal material.

The aluminum alloy battery casing is an important supporting industry for the new energy vehicle industry. At the level of the established product structure and technology, there is a fixed ratio of 1:1 between the aluminum alloy battery casing and the new energy vehicle. Therefore, the market demand, industrial scale, and development space of aluminum alloy battery casings are closely related to the downstream, and the development prospects are broad.
