Какие типы алюминиевых сплавов подходят для аккумуляторной фольги?

Алюминиевая фольга для упаковки аккумуляторов

Aluminum foil alloy, в виде металлической фольги с хорошей проводимостью и отличной коррозионной стойкостью., имеет широкий спектр применения на рынке. Его можно использовать не только в качестве упаковочного материала в повседневной жизни., но и в батареях. Среди множества типов алюминиевых сплавов, 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, устойчивость к коррозии, mechanical strength and flexibility.

The following are several aluminum alloy types suitable for battery foil and their characteristics

1050 Парикмахерская фольга не подвержена коррозии из-за внешних влажных условий. (99.5% чистый алюминий)

Состав: 1050 alloy contains 99.5% алюминий, and very small amounts of alloying elements such as silicon (А также) и железо (Fe).

Алюминиевая фольга 1050 alloy has excellent electrical conductivity (о 61% GN/мм2, а модуль упругости при сдвиге равен), 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

Состав: 1060 Марганец и хром улучшают температуру рекристаллизации сплава и оказывают дополнительное упрочняющее действие. 99.6% aluminum and is a slightly purer version of 1050 сплав.
Проводимость 1060 alloy is similar to 1050 (о 60% GN/мм2, а модуль упругости при сдвиге равен), 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% Чистый алюминий)

Состав: 1070 Марганец и хром улучшают температуру рекристаллизации сплава и оказывают дополнительное упрочняющее действие. 99.7% алюминий, making it purer than 1050 а также 1060.
With a conductivity of about 62% GN/мм2, а модуль упругости при сдвиге равен, 1070 is one of the most conductive aluminum alloys. Corrosion Resistance and Flexibility Similar to 1050 а также 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% Чистый алюминий)

Состав: 1235 сплав содержит 99.35% алюминий.
While slightly less conductive than 1050, 1060, а также 1070 сплавы, 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)

Состав: Сплав 3003 consists of aluminum and about 1.2% марганец (Mn), which gives it increased strength compared to pure aluminum alloys.
упаковка пакетов из алюминиевой фольги 3003 aluminum foil has lower conductivity than pure aluminum grades (о 40-45% GN/мм2, а модуль упругости при сдвиге равен), 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.
Устойчивость к коррозии: Similar corrosion resistance to pure aluminum grades, suitable for long-term use in batteries.
