If you want to know which material is better used in power battery shell, first you should know what is the power battery. Although there is no clear definition of power battery academia, but the global electric vehicle industry basic agreement: the battery provide driving power for the electric vehicle is known as the power battery, including the traditional lead-acid batteries, nickel-metal hydride batteries and emerging lithium-ion power Lithium batteries. As car lightweight is respected in the global currently, aluminum is the best choice, the power battery shell material preferred 3003 aluminum coil than other material.
3003 aluminum coil has good form-ability, mainly used in deep drawing materials, use 3003 aluminum alloy to produce stamping parts, models, shells with good surface, good plasticity, pressure resistance and many other advantages. 3003 aluminum alloy power battery shell with impact, not easy to break and leak and meet the requirements of strength and rigidity, and aluminum alloy has low density, light weight, can reduce the battery weight, improve battery capacity density, So that the battery works stable, indirectly reduce the weight of the vehicle, increase the endurance of vehicle. 3003 power battery shell material is one of the featured products of BT Aluminum, 3003 aluminum coil is produced with mature technology, excellent quality, global distribution. 3003 aluminum coil has the following performance, excellent forming characteristics, high corrosion resistance, good weld-ability and conductivity.
