Aluminium’s unique properties make it the go-to material for battery applications. With its high conductivity, the battery’s internal and external electrical resistance can be kept low, allowing high charging speeds. Aluminum is the material of choice for li ion battery casings due to its lightweight nature, excellent corrosion resistance, superior thermal conductivity, and ease of processing. [pdf]
Compared to other metals like iron, stainless steel, or copper, aluminum meets the unique demands of lithium batteries, ensuring safety, stability, and performance while minimizing weight and production costs. By leveraging aluminum casings, manufacturers can produce reliable, high-performance batteries for a wide range of applications.
At HDM, we have developed aluminum alloy sheets that are perfect for cylindrical, prismatic, and pouch-shaped lithium-ion battery cases based on the current application of lithium-ion batteries in various fields. Our aluminum alloy materials are user-friendly, compatible with various deep-drawing processes.
Chalco's production of power battery aluminum trays mostly uses 6-series 6061 aluminum plate as the raw material for battery aluminum trays, which can meet the characteristics of high precision, corrosion resistance, high temperature resistance, and impact resistance to protect the battery core.
The internal environment of a lithium battery contains complex chemical components, including electrolytes and electrodes. Aluminum is chemically stable and reacts minimally with these materials, ensuring the battery’s stability. Compared to iron, aluminum’s compatibility with lithium battery chemistry helps avoid unwanted chemical reactions.
Aluminum alloy is a commonly used material for power batteries, and there is an urgent need to focus on research, development, and upgrading of products and alloy materials. At present, the conventional aluminum alloys used in power batteries mainly include 1-series, 3-series, 5-series, and 6-series.
Efficient heat dissipation is essential for lithium batteries as they generate heat during charge and discharge cycles. Aluminum’s superior thermal conductivity helps transfer heat away from the battery core, maintaining a stable operating temperature and reducing the risk of thermal runaway. 4. Easy to Process
