Advantages of using aluminium alloys for battery enclosure making

The battery enclosure is the load-bearing part of the new energy power battery. It is mainly used to protect the lithium battery from damage when it is impacted and squeezed by the outside. Power battery enclosure materials are generally divided into aluminum and steel. For lightweight considerations, power batteries enclosure tends to use aluminum alloy materials. Aluminum alloys play a vital role in the realm of emerging energy batteries, particularly when it comes to encasing batteries. The battery enclosure, a pivotal component, shields the internal battery components from external surroundings. It’s imperative that this casing possesses commendable thermal conductivity and structural robustness to ensure the battery’s security and consistent performance.

Power battery enclosure generally uses 3003 h14 aluminum plates, and the thickness is generally around 0.8-3mm. 3003 aluminum alloy materials have low density and soft materials. They have the advantages of being easy to stretch the aluminum alloy battery casing as a whole. The width and length can be customized according to the actual needs of users.
