To know which material is better for the power battery casing, the first thing to know is the power battery. Although there is no clear definition of the power battery academic community, the global electric vehicle industry basically agrees that batteries that provide driving power for electric vehicles are called power batteries, including traditional lead-acid batteries, nickel-hydrogen batteries, and emerging lithium-ion power. Lithium batteries are currently being promoted in the world for lightweighting, and aluminum is a better choice. These power battery casings are preferably 3003 aluminum foil.

3003 electronic foil has good formability, mainly used in deep-drawn materials. It uses 3003 aluminum alloy products as stamping parts, models and shells, etc. It has many advantages such as good surface, good plasticity and pressure resistance. The power battery case made of 3003 aluminum alloy product has impact resistance, non-breaking and leakage, and can meet the requirements of strength and rigidity of the power battery case, and the aluminum alloy has small density and light weight, which can reduce the weight of the battery and increase the battery capacity density. To make the battery work stable, indirectly reduce the quality of the vehicle and increase the battery life.

3003 power battery shell is one of the advantages of Mingtai Aluminum, with mature technology, excellent quality and global distribution. The 3003 alloy aluminum coil has the following 4-point performance:

1. Excellent forming and processing characteristics, high corrosion resistance, good weldability and electrical conductivity.

2. The surface is flat, plastic and pressure resistant.

3, with impact resistance, not easy to break and leak, can meet the strength and rigidity requirements of the power battery casing.

4, lightweight automotive aluminum, low density, light weight, can reduce the weight of the vehicle, improve vehicle life.
