New energy battery shell aluminium anodised material
Time :2021-05-13
At present, new energy electric vehicles have become the key development direction of the automotive industry. Power battery is one of the core components of new energy electric vehicles. Its packaging process is very important in the process of power battery production. Good packaging determines the safety and life of the battery. Therefore, choose a good power battery aluminum shell material , And choose the optimal packaging process according to the material characteristics, which is particularly important for the safety and service life of the battery
At present, 3003 aluminum alloy is generally used for New energy battery shell aluminum anodised material, because this material has easy processing and forming, high temperature corrosion resistance, good heat transfer and electrical conductivity. The power battery aluminum shell of 3003 aluminum alloy (except the shell cover) can be stretched and formed at one time. Compared with the stainless steel shell, the welding process of the bottom of the box can be omitted. Good plasticity, so it can be made into shell products of various shapes.

The application of New energy battery shell aluminum anodised material has become the main way to reduce the weight of automobiles, and it is more and more widely used in the field of auto parts. Three different types of aluminum materials, rolled alumina plate, extruded aluminum profile, and cast aluminum, have been applied in batches in different battery shell projects, and have become the mainstream technology route for power battery system shells. Die-cast aluminum is widely used in hybrid power and other small power battery shells, and large power battery shells are mainly made of aluminum profiles and aluminum plate welded structures.
