For example, a lithium-ion battery cell will have an anode made from lithium, lithium-alloying materials, graphite, intermetallic, and silicon. The cathode will typically be made of lithium-metal oxides, rechargeable lithium oxides, olivine, and vanadium oxides.
Aluminum battery cases are made entirely from aluminum or aluminum alloys, providing high strength-to-weight ratio, good heat dissipation, and corrosion resistance.
All batteries will have components such as anodes, cathodes, and electrolytes, yet these components will be made of specific materials based on whether a customer selects a lithium-based battery, alkaline battery, or nickel-based battery.
For batteries that will be completely inserted into the application, the standard shrink wrapping or vacuum formed plastic will be standard. If the batteries will be mounted into the device, such as on the handle or in a separate housing that will need to be accessible, injection molded plastic is commonly used.
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.
