Aluminiumsfolie spiller en afgørende rolle i konstruktionen af lithium-ion-batterier. Der er mange modeller i 1000-8000 serie legeringer, der kan bruges i batteriproduktion.
Ren aluminiumsfolie: Ren aluminiumsfolie, der almindeligvis anvendes i lithiumbatterier, omfatter forskellige legeringskvaliteter som f.eks 1060, 1050, 1145, og 1235. Disse folier er normalt i forskellige tilstande, såsom O, H14, H18, H24, H22.
Især legering 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, som f.eks 3003 og 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, formbarhed, strength and cost considerations.
