3003 Aluminum Strip for Battery Shell

A basic advantage of aluminum alloys over steel is that they are lighter. Why are aluminum alloys lighter? Because the density of aluminum is relatively small, the density of aluminum alloy materials is 2.5-2.8g/cm3. The aluminum sheet and strips are mainly used for body panels, door skins, heat dissipation systems, battery shells, and battery foils.

New energy vehicles are becoming more and more common, and compared with fuel vehicles, they are of great significance in saving resources and protecting the environment. However, the short cruising range of new energy vehicles is a problem that needs continuous efforts to solve now and in the future.

The batteries that provide driving power for electric vehicles are called power batteries, including traditional lead-acid batteries, nickel-metal hydride batteries, and emerging lithium-ion power lithium batteries. Currently, the world is promoting lightweight vehicles, and aluminum is the best choice. The aluminum strip for battery shell chooses 3003 aluminum alloy.

The power battery shell made of 3003 aluminum sheet is impact resistant, not easy to break and leak, and can meet the strength and rigidity requirements of the power battery casing. The aluminum alloy has low density and light weight, which can reduce the weight of the battery and improve the battery capacity density, making the battery work stably, indirectly reducing the weight of the vehicle and increasing the vehicle's endurance.

3003 aluminum strip is an AL-Mn alloy. Due to the manganese alloy element, this product has excellent anti-rust properties. It is used for processing parts and components that require good formability, high corrosion resistance and good weldability, or the parts hat requires both these properties and higher strength than 1XXX series alloys.

3003 alloy also has excellent corrosion resistance. The corrosion resistance in the atmosphere and seawater is equivalent to that of pure aluminum. The corrosion resistance in dilute hydrochloric acid solution (1:5) is higher than that of pure aluminum and lower than that of aluminum-magnesium alloy.

The square lithium battery shell is made of 3003-H14 aluminum strip. In the manufacturing of electric vehicles, 3003H14 power battery casing is the main material of its core power battery. The 3003 aluminum alloy for battery shell from "0 state" to "H14" state. The fundamental reason lies in the advancement of technology.

As a traditional manual punching state, 3003-0 aluminum is of low production efficiency and low yield rate. 3003-H14 aluminum strip is more suitable for automatic and semi-automatic punching, and has higher production efficiency.
