Battery is one of the core components of new energy electric vehicles. Its encapsulation process is very important in the production process of power battery, and good encapsulation determines the safety and service life of the battery, therefore, it is especially important to select an optimal aluminum power battery shell material and choose the optimal encapsulation process according to the characteristics of the shell material, which is especially important for the safety and service life of the battery.
At present, the aluminum power battery case for electric vehicles generally uses 3003 aluminum alloy. This material has easy processing and shaping, high temperature corrosion resistance, good heat transfer and electrical conductivity. 3003 aluminum alloy aluminum power battery shell (except for the shell cover) can be formed in one stretch, compared with stainless steel shell, can save the box bottom welding process.
