3003 aluminum discs for power battery housing

Power battery housing is a novel application of aluminum discs, developed only decades ago. Boasting perfect properties, 3003 aluminum becomes the ideal alloy for battery housing of new energy vehicles. 3003 is mainly aluminum-manganese alloy, and the main alloying element is manganese. This alloy is easy to be formed, and is characterized by good corrosion resistance at high temperatures, as well as good heat and electricity conductivity. The boiling point temperatures of aluminum and manganese have little difference, and there will be no problems such as deterioration of weld quality resulting from the burning of metal elements during welding. In addition, The aluminum power battery shells of 3003 aluminum alloy (except the shell cover) can be stretched and formed at one time. Compared with the stainless steel shells, the welding process of the bottom of the box can be omitted.

The importance of power battery housing material is obvious. As a core part of a new energy automobile, batteries must be enclosed tightly and safely, otherwise their service life might be reduced substantially. Therefore, choosing a better aluminum power battery shell material and adopting a better packaging process according to the characteristics of the shell material is particularly important for the safety and service life of the battery. 3003 aluminum discs, light and anti-rust, can be stamped into battery shells without the melding process, which greatly enhances the sealing effect of batteries.

The circles are expected to play an even bigger role in future automobile industry, for an increasing number of vehicle manufacturers take electric cars and buses into their business scope. This will be a trend, since electricity is a renewable energy in comparison to traditional fuels like petrol and gas.
