Power battery shell materials are generally divided into aluminum shell and steel shell, using aluminum shell is much lighter and safer than steel shell packaging. 3003 aluminum foil is the main material for power battery shell. The lithium battery with the same capacity from the worst results, even if the battery in case of explosion, lithium battery aluminum shell is also much weaker than the burst force of the steel shell, resulting in a lower hazard.

Henan Henry Aluminum has a considerable say in the R&D and production of aluminum ribbons for power battery cases. The company's research and development “Aluminum Plates, Aluminum Strips for Power Battery and Its Production Methods” won the national invention patent. The aluminum shell for battery shell is mainly made of 3003 aluminum foil. The power battery shell processed by aluminum has the characteristics of easy processing, high temperature resistance, corrosion resistance, excellent thermal conductivity and excellent electrical conductivity. The aluminum power battery case made of 3003 aluminum foil (except the shell cover) can be stretched at one time. Compared with the stainless steel shell, the bottom welding process can be omitted, and the metal element will not be burned during welding. The problem is that the weld quality deteriorates.
