The battery shell is the carrier of the electric vehicle power battery, mainly used to protect the lithium battery from damage when it is hit or squeezed by the outside world. The power battery shell is generally divided into aluminum shell and steel shell according to the material. Due to the light weight, high specific strength and good corrosion resistance and stability of the aluminum shell, it has become the mainstream of new energy power battery shell. With the hot market of new energy vehicles, aluminum materials for battery shells will usher in greater development.
The power battery shell usually uses 3003 aluminum coil, the main alloy element is manganese. This material has the advantages of easy processing, high temperature corrosion resistance, good heat transfer and conductivity. The power battery aluminum shell of 3003 aluminum alloy (except the shell cover) can be stretched and formed at one time. Compared with the stainless steel shell, the box bottom welding process can be omitted.
The 3003 aluminum alloy material has the advantages of low density and soft material, and is easy to stretch and form the power battery aluminum shell as a whole. It has been used for battery packaging by many companies. New energy electric vehicles require a large number of lithium battery combination modules. The low density of aluminum alloy can reduce the weight of the battery and achieve lightweight development.
As a large-scale aluminum sheet and foil manufacturer, Mingtai Aluminum has a deep understanding of aluminum used in new energy power batteries. At present, the sales of battery foil, electronic foil, aluminum-plastic film foil, battery shell, water-cooled plate, battery tray and other products in the new energy field are accelerating.
Battery shell materials have special requirements on chemical composition when purchasing ingots and other 3003 aluminum alloys. Raw material manufacturers need to strictly control them before they can produce raw materials suitable for battery shell materials. Mingtai Aluminum strictly selects raw materials, controls production processes, and ensures excellent product quality. At present, the company's power battery aluminum plate has occupied a certain share in the power battery industry and is well received by users!
