The power battery casing is designed with square and rounded corners. The aluminum shell is usually made of 3003 aluminum-manganese alloy. The main alloy components are Mn, Cu, Mg, Si, Fe, etc. These five alloys play different roles. The effects such as Cu and Mg are to improve strength and hardness, Mn to improve corrosion resistance, Si to enhance the heat treatment effect of magnesium-containing aluminum alloy, and Fe to improve high temperature strength.
The outer casing of the battery can be made of 3003 aluminum plate. The use of 3003 aluminum plate can increase the conductivity of the power battery. At the same time, the density of aluminum is small, the volume of the lithium battery is increased, and the performance and stability of the group are better.
