Folia de aluminiu joacă un rol vital în construcția bateriilor litiu-ion. Există multe modele în 1000-8000 aliaje de serie care pot fi utilizate în producția de baterii.
Folie de aluminiu pură: Folia de aluminiu pur folosită în mod obișnuit în bateriile cu litiu include diferite grade de aliaje, cum ar fi 1060, 1050, 1145, şi 1235. Aceste folii sunt de obicei în diferite stări, cum ar fi O, H14, H18, H24, H22.
Mai ales aliajul 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, ca 3003 şi 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.
