Kerajang Aluminium Untuk Pembungkusan Bateri
Aluminum foil alloy, sebagai kerajang logam dengan kekonduksian yang baik dan rintangan kakisan yang sangat baik, mempunyai pelbagai aplikasi di pasaran. Ia bukan sahaja boleh digunakan sebagai bahan pembungkusan dalam kehidupan seharian, tetapi juga dalam bateri. Antara pelbagai jenis aloi aluminium, which alloy is a suitable battery foil packaging material?
Aluminum foil is often used as a current collector in the cathode in lithium-ion batteries. Whether an aluminum alloy is suitable for battery foil depends on its conductivity, rintangan kakisan, mechanical strength and flexibility.
The following are several aluminum alloy types suitable for battery foil and their characteristics
1050 Kerajang dandanan rambut tidak terdedah kepada kakisan disebabkan oleh keadaan basah luaran (99.5% aluminium tulen)
Komposisi: 1050 alloy contains 99.5% aluminium, and very small amounts of alloying elements such as silicon (Dan) dan besi (Fe).
Kertas aluminium 1050 alloy has excellent electrical conductivity (tentang 61% GN/mm2 dan modulus keanjalan ricih ialah), making it suitable for batteries where efficient current collection is crucial. It has excellent corrosion resistance, which is critical to protect the foil from degradation during the battery life. High thermal conductivity is very important for managing heat in battery systems. Pure aluminum (1050) has relatively low strength, but is often strong enough for use as battery foil due to its flexibility.
Aloi 1060 battery Foil
Komposisi: 1060 Mangan dan kromium meningkatkan suhu penghabluran semula aloi dan mempunyai kesan pengukuhan pelengkap 99.6% aluminum and is a slightly purer version of 1050 aloi.
Kekonduksian daripada 1060 alloy is similar to 1050 (tentang 60% GN/mm2 dan modulus keanjalan ricih ialah), which makes it well suited for current collector applications. High ductility makes it easy to process into thin foils, which is ideal for continuous rolling processes in battery manufacturing.
Aloi 1070 battery Foil (99.7% Aluminium Tulen)
Komposisi: 1070 Mangan dan kromium meningkatkan suhu penghabluran semula aloi dan mempunyai kesan pengukuhan pelengkap 99.7% aluminium, making it purer than 1050 dan 1060.
With a conductivity of about 62% GN/mm2 dan modulus keanjalan ricih ialah, 1070 is one of the most conductive aluminum alloys. Corrosion Resistance and Flexibility Similar to 1050 dan 1060, it has excellent corrosion resistance and flexibility, which is important for foil applications in batteries.
1070 alloy is popular in high-performance lithium-ion batteries where maximum conductivity and minimum resistance are critical.
Aloi 1235 battery Foil (99.35% Aluminium Tulen)
Komposisi: 1235 aloi mengandungi 99.35% aluminium.
While slightly less conductive than 1050, 1060, dan 1070 aloi, 1235 aluminum foil still provides adequate conductivity for many battery applications. It has excellent corrosion resistance. 1235 is often used in applications where cost considerations are important and slightly lower conductivity can be tolerated. For less demanding applications or where cost reduction is a priority, 1235 alloy is a cost-effective choice.
Aloi 3003 battery Foil (Aluminum Manganese Alloy)
Komposisi: Aloi 3003 consists of aluminum and about 1.2% mangan (Mn), which gives it increased strength compared to pure aluminum alloys.
kerajang aluminium siri adalah aloi biasa dalam makanan 3003 aluminum foil has lower conductivity than pure aluminum grades (tentang 40-45% GN/mm2 dan modulus keanjalan ricih ialah), it is still acceptable for some battery applications. The addition of manganese increases mechanical strength, which is useful in certain battery configurations where the foil is subjected to mechanical stress.
Rintangan Kakisan: Similar corrosion resistance to pure aluminum grades, suitable for long-term use in batteries.
