It is common practice to use aluminum sheet for power battery shells, especially for battery packs in electric vehicles (EV) and hybrid electric vehicles (HEV). Aluminum sheet as a battery shell material has the following advantages:
Of course, there are some challenges in using aluminum sheets, such as cost issues and slightly lower strength under certain conditions compared to other materials (such as steel). However, these problems can be improved through alloying and special treatment methods.
In practical applications, the design of the battery casing also needs to consider the requirements of waterproof and dustproof level, mechanical strength, safety and other aspects. Therefore, manufacturers usually choose the most suitable materials and technical solutions according to specific usage scenarios and needs.
