La feuille d'aluminium joue un rôle essentiel dans la construction des batteries lithium-ion. Il existe de nombreux modèles dans 1000-8000 alliages en série pouvant être utilisés dans la production de batteries.
Feuille d'aluminium pur: La feuille d'aluminium pur couramment utilisée dans les batteries au lithium comprend diverses qualités d'alliage telles que 1060, 1050, 1145, et 1235. Ces foils sont généralement dans différents états tels que O, H14, H18, H24, H22.
Surtout l'alliage 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, tel que 3003 et 3104, which offer a balance of strength and formability. En plus, 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. Dans l'ensemble, the selection of aluminum alloys for battery applications depends on factors such as conductivity, formabilité, strength and cost considerations.
