Why choose 3003-H14 aluminum strip for power battery shell

The aluminum shell of automobile power battery is made of 3003-H14 aluminum strip or aluminum coil. because,

1. This material is easy to process and form, high temperature corrosion resistance, good heat transfer and electrical conductivity;

2. The power battery aluminum shell (except the shell cover) using 3003 aluminum alloy can be drawn and formed at one time. Compared with the stainless steel shell, the welding process of the bottom of the box can be omitted;

3. 3003 aluminum alloy is aluminum-manganese alloy, and the main alloying element is manganese. The boiling point temperature of aluminum and manganese is not much different, and there will be no problems such as the deterioration of weld quality due to the burning of metal elements during welding.

The role of 3003 aluminum alloy in the battery shell

The 3003 aluminum alloy material has the advantages of low density and soft material, and has the advantages of easy overall drawing and forming of the aluminum shell of the power battery, and has been used by many enterprises for battery packaging. Aluminum alloys are much less dense than traditional stainless steel encapsulation materials.

In order to increase the cruising range, new energy electric vehicles need a large number of lithium battery combination modules. Each module is composed of several battery boxes. In this way, the quality of each battery box has a great impact on the quality of the entire battery module. In order to reduce the quality of the battery, it is an inevitable choice to use 3003 aluminum alloy material to make the battery case.

Advantages of aluminum materials for power battery shells

1. Explosion-proof performance

2. Anti-aging properties

3. Long service life

4. Flame retardant, smokeless, nontoxic
