Aluminum Foils for Li-ion Batteries | Haomei Aluminum
Lithium-ion battery foil manufacturing process. The manufacturing of lithium-ion battery aluminum foil involves precise processes to ensure the desired properties and performance characteristics. The main manufacturing steps include: 1. Aluminum ingot casting. The process begins by casting high-purity aluminum ingots.
Making aluminium foil. Alufoil is a very thin sheet of aluminium ranging from about 0.006 mm to the upper ISO defined limit of 0.2 mm (200 µm). It is produced by first rolling heated ingots (hot rolling) down to coils of thickness between 2 and 4 mm. The coils are then successively cold rolled to the required foil thicknesses.
Coating involves applying the slurry from the mixing process onto thin metallic foils. Copper foil with a typical thickness of 6 to 15 μm is used for the anode. Aluminum foil is used for the cathode; its typical thickness is 15 to 25 μm. The metallic foils form the electrode base and the current conductor.
