Aluminium Foil Untuk Kemasan Baterai
Aluminum foil alloy, sebagai foil logam dengan konduktivitas yang baik dan ketahanan korosi yang sangat baik, memiliki berbagai aplikasi di pasar. Tidak hanya bisa digunakan sebagai bahan pengemas dalam kehidupan sehari-hari, tetapi juga pada baterai. Di antara sekian banyak jenis paduan 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, tahan korosi, mechanical strength and flexibility.
The following are several aluminum alloy types suitable for battery foil and their characteristics
1050 F (99.5% aluminium murni)
Komposisi: 1050 alloy contains 99.5% aluminium, and very small amounts of alloying elements such as silicon (Dan) dan besi (Fe).
Alumunium foil 1050 alloy has excellent electrical conductivity (tentang 61% GN/mm2 dan modulus elastisitas geser adalah), 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.
paduan 1060 battery Foil
Komposisi: 1060 Mangan dan kromium meningkatkan suhu rekristalisasi paduan dan memiliki efek penguatan yang saling melengkapi 99.6% aluminum and is a slightly purer version of 1050 paduan.
Konduktivitas dari 1060 alloy is similar to 1050 (tentang 60% GN/mm2 dan modulus elastisitas geser adalah), 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.
paduan 1070 battery Foil (99.7% Aluminium Murni)
Komposisi: 1070 Mangan dan kromium meningkatkan suhu rekristalisasi paduan dan memiliki efek penguatan yang saling melengkapi 99.7% aluminium, making it purer than 1050 dan 1060.
With a conductivity of about 62% GN/mm2 dan modulus elastisitas geser adalah, 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.
paduan 1235 battery Foil (99.35% Aluminium Murni)
Komposisi: 1235 paduan mengandung 99.35% aluminium.
While slightly less conductive than 1050, 1060, dan 1070 paduan, 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.
paduan 3003 battery Foil (Aluminum Manganese Alloy)
Komposisi: paduan 3003 consists of aluminum and about 1.2% mangan (M N), which gives it increased strength compared to pure aluminum alloys.
seri aluminium foil adalah paduan umum dalam makanan 3003 aluminum foil has lower conductivity than pure aluminum grades (tentang 40-45% GN/mm2 dan modulus elastisitas geser adalah), 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.
Tahan korosi: Similar corrosion resistance to pure aluminum grades, suitable for long-term use in batteries.
