Alumīnija folijai ir būtiska loma litija jonu akumulatoru konstrukcijā. Ir daudz modeļu 1000-8000 sērijas sakausējumi, kurus var izmantot akumulatoru ražošanā.
Tīra alumīnija folija: Tīra alumīnija folija, ko parasti izmanto litija baterijās, ietver dažādas sakausējuma kategorijas, piemēram, 1060, 1050, 1145, un 1235. Šīs folijas parasti ir dažādos stāvokļos, piemēram, O, H14, H18, H24, H22.
Īpaši sakausējums 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, piemēram, 3003 un 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, formējamība, strength and cost considerations.
