As we all know, this year is the first year of the development of new energy vehicles, but also the year of the rapid start of the power battery. Power battery as the core of new energy vehicles, representative of the PACK battery pack, and the core composition of the battery cell, the current shape of the battery cell classification mainstream into three categories: square shell, cylindrical, soft pack (polymer batteries), and Mingtai aluminum can produce good quality, a large number of soft pack batteries with 8021 aluminum foil.

As a material for lithium batteries, safety requirements are also placed on 8021 aluminium foil. Hormel 8021 aluminium foil for lithium batteries should meet the following requirements.

1. The aluminium foil has high cleanliness requirements: no debris or dust shall be mixed in the production process, which will seriously damage the battery during charging and discharging.

2. High requirements for the shape of the aluminium foil: the positive material on the surface of the aluminium foil will have an impact on the service life and range of the battery;

3, high mechanical properties of aluminium foil: high tensile strength and high elongation are required, while maintaining the same purity of aluminium.

4. High requirements for thickness and pinholes: thinner aluminium foils will inevitably lead to an increased number of pinholes being formed, which will result in higher requirements for foils with broken strips in the rolling process.

5. High surface requirements: The surface of aluminium foil must not have various surface defects, such as dark bright spots, which place considerable demands on cleanliness;
