Karatasi ya alumini ina jukumu muhimu katika ujenzi wa betri za lithiamu-ioni. Kuna mifano mingi katika 1000-8000 aloi za mfululizo ambazo zinaweza kutumika katika uzalishaji wa betri.
Karatasi safi ya alumini: Karatasi safi ya alumini inayotumika kwa kawaida katika betri za lithiamu inajumuisha aina mbalimbali za aloi kama vile 1060, 1050, 1145, na 1235. Foili hizi kawaida huwa katika hali tofauti kama vile O, H14, H18, H24, H22.
Hasa aloi 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, kama vile 3003 na 3104, which offer a balance of strength and formability. Zaidi ya hayo, 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.
