Which aluminum foil alloys can be used in batteries?

Aluminum foil plays a vital role in the construction of lithium-ion batteries. There are many models in the 1000-8000 series alloys that can be used in battery production.

Pure aluminum foil: Pure aluminum foil commonly used in lithium batteries includes various alloy grades such as 1060, 1050, 1145, and 1235.
These foils are usually in different states such as O, H14, H18, H24, H22.

Especially alloy 1145. The alloy is known for its high electrical conductivity, low impurity content and good formability, making it suitable for use as a current collector in batteries.

Other aluminum alloys that can be used in battery applications include the 3xxx series of alloys, such as 3003 and 3104, which offer a balance of strength and formability. Additionally, some battery manufacturers may use 8xxx series alloys to meet specific performance requirements.

Aluminum-silicon alloy foil: Aluminum foil containing silicon alloy is a promising anode material for next-generation lithium-ion batteries. They offer a balance between low cost, environmental friendliness and high performance.

Researchers found that aluminum foil anodes exhibit higher performance and stability in solid-state batteries compared to traditional lithium-ion batteries. Overall, the selection of aluminum alloys for battery applications depends on factors such as conductivity, formability, strength and cost considerations.
