Lightweight battery shell foil —Mingtai Aluminum

2019-10-27

The battery shell foil is a polymer shell on the liquid lithium-ion battery sleeve, which is applied to various types of lithium batteries such as a soft lithium battery and a polymer lithium battery.This kind of shell plays an important role in the battery itself. So what is the material of the battery shell foil? What are its functions? Please follow the editor to understand:

Material of battery shell foil

The battery shell foil is generally made of aluminum or steel, which are relatively common on the market. Aluminum alloy has the advantages of low density, high strength, good plasticity, excellent conductivity, thermal conductivity and corrosion resistance, and is widely used in industry. There are also many battery cases made of steel shells, but the density of steel is larger,aluminum shell is lighter than steel shell for lithium battery of the same capacity. Because the density of aluminum is small, it can be made lighter.

Mingtai Aluminum's battery shell foil

The main alloy number of Mingtai battery shell foil are 8021 aluminum foil and 8079 aluminum foil, mainly in O state, and Hx2,Hx4 state can also be used to make battery shell. Advantages of aluminum battery shell foil:

1. The density of aluminum is lower than other metals, its own weight is relatively light. Being used as a battery shell does not place a great burden on the battery itself.

2. 2.Aluminum has good anti-oxidation and anti-corrosion function. Therefore, the use of aluminum battery shell material can ensure the quality of the battery, reduce the battery replacement frequency, and indirectly protect the environment.

8021 aluminum foil and 8079 aluminum foil are Mingtai hot selling products, It has good deep drawing performance, good resistance to electrolyte corrosion and high heat sealing strength.The thickness range of production is 0.015mm-0.2mm. It can be customized according to customer requirements. It is the preferred aluminum material for battery shell foil.

Due to the high technical barriers, the current global battery shell manufacturers are mainly concentrated in Japan and South Korea. Only a few domestic manufacturers have high technical indicators, and Mingtai aluminum industry has become one of them with its own strength. If you need battery aluminum foil base material, please consult customer service.
