배터리 포장용 알루미늄 호일
Aluminum foil alloy, 전도성이 좋고 내식성이 우수한 금속박으로, 시장에는 다양한 응용 분야가 있습니다.. 일상생활에서 포장재로 사용할 수 있을 뿐만 아니라, 하지만 배터리에도. 많은 알루미늄 합금 종류 중에서, 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, 내식성, mechanical strength and flexibility.
The following are several aluminum alloy types suitable for battery foil and their characteristics
1050 미용 포일은 외부 습한 조건으로 인해 부식되기 쉽지 않습니다. (99.5% 순수한 알루미늄)
구성: 1050 alloy contains 99.5% 알류미늄, and very small amounts of alloying elements such as silicon (그리고) 그리고 철 (철).
알루미늄 호일 1050 alloy has excellent electrical conductivity (~에 대한 61% GN/mm2 및 전단 탄성 계수는), 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.
합금 1060 battery Foil
구성: 1060 망간 및 크롬은 합금의 재결정 온도를 향상시키고 보완적인 강화 효과가 있습니다. 99.6% aluminum and is a slightly purer version of 1050 합금.
전도도 1060 alloy is similar to 1050 (~에 대한 60% GN/mm2 및 전단 탄성 계수는), 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.
합금 1070 battery Foil (99.7% 순수 알루미늄)
구성: 1070 망간 및 크롬은 합금의 재결정 온도를 향상시키고 보완적인 강화 효과가 있습니다. 99.7% 알류미늄, making it purer than 1050 그리고 1060.
With a conductivity of about 62% GN/mm2 및 전단 탄성 계수는, 1070 is one of the most conductive aluminum alloys. Corrosion Resistance and Flexibility Similar to 1050 그리고 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.
합금 1235 battery Foil (99.35% 순수 알루미늄)
구성: 1235 합금 포함 99.35% 알류미늄.
While slightly less conductive than 1050, 1060, 그리고 1070 합금, 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.
합금 3003 battery Foil (Aluminum Manganese Alloy)
구성: 합금 3003 consists of aluminum and about 1.2% 망간 (미네소타), which gives it increased strength compared to pure aluminum alloys.
일반적인 포장 백은 일반적으로 합성 플라스틱으로 만들어집니다. 3003 aluminum foil has lower conductivity than pure aluminum grades (~에 대한 40-45% GN/mm2 및 전단 탄성 계수는), 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.
내식성: Similar corrosion resistance to pure aluminum grades, suitable for long-term use in batteries.
