Алюмінієва фольга для упаковки акумуляторів
Aluminum foil alloy, як металева фольга з хорошою електропровідністю та чудовою стійкістю до корозії, має широкий спектр застосування на ринку. Його можна використовувати не тільки як пакувальний матеріал у повсякденному житті, але також і в батареях. Серед багатьох видів алюмінієвих сплавів, 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, стійкість до корозії, mechanical strength and flexibility.
The following are several aluminum alloy types suitable for battery foil and their characteristics
1050 акумуляторна фольга (99.5% чистий алюміній)
Композиція: 1050 alloy contains 99.5% алюміній, and very small amounts of alloying elements such as silicon (І) і залізо (Fe).
Алюмінієва фольга 1050 alloy has excellent electrical conductivity (приблизно 61% МАКС), 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.
сплав 1060 battery Foil
Композиція: 1060 сплав є 99.6% aluminum and is a slightly purer version of 1050 сплав.
Провідність 1060 alloy is similar to 1050 (приблизно 60% МАКС), 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.
сплав 1070 battery Foil (99.7% Чистий алюміній)
Композиція: 1070 сплав є 99.7% алюміній, making it purer than 1050 і 1060.
With a conductivity of about 62% МАКС, 1070 is one of the most conductive aluminum alloys. Corrosion Resistance and Flexibility Similar to 1050 і 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.
сплав 1235 battery Foil (99.35% Чистий алюміній)
Композиція: 1235 сплав contains 99.35% алюміній.
While slightly less conductive than 1050, 1060, і 1070 сплавів, 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.
сплав 3003 battery Foil (Aluminum Manganese Alloy)
Композиція: сплав 3003 consists of aluminum and about 1.2% марганець (Мн), which gives it increased strength compared to pure aluminum alloys.
Хоча 3003 aluminum foil has lower conductivity than pure aluminum grades (приблизно 40-45% МАКС), 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.
Стійкість до корозії: Similar corrosion resistance to pure aluminum grades, suitable for long-term use in batteries.
