How to choose Battery Shell Foil?

Battery aluminum foil is one of the base materials for new energy vehicle lithium batteries. Different batteries have different requirements for casing materials. Choosing the right casing foil is crucial to ensure optimal performance and safety. When choosing battery casing foil, we should pay attention to the thickness and strength of the foil. The foil should be able to withstand the mechanical stress the battery may encounter during its lifetime. In addition, the foil should also have good electrical conductivity to facilitate the efficient flow of electrical current. At the same time, the housing foil needs to have good adhesion properties to ensure a good combination with other components.
