Alumiinifoliolla on tärkeä rooli litiumioniakkujen valmistuksessa. Siinä on monia malleja 1000-8000 sarjan metalliseokset, joita voidaan käyttää akkutuotannossa.
Puhdas alumiinifolio: Litiumakuissa yleisesti käytetty puhdas alumiinifolio sisältää erilaisia metalliseoslaatuja, kuten 1060, 1050, 1145, ja 1235. Nämä kalvot ovat yleensä eri tilassa, kuten O, H14, H18, H24, H22.
Varsinkin metalliseos 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, kuten 3003 ja 3104, which offer a balance of strength and formability. Lisäksi, 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. Yleensä ottaen, the selection of aluminum alloys for battery applications depends on factors such as conductivity, muotoiltavuus, strength and cost considerations.
