Lithium Cell Battery Aluminum Shell
Products Description
The lithium cell battery Aluminum shell is a thin-walled precision metal forming component, typically manufactured through a deep drawing and stamping composite forming process. Its overall structure has a regular geometric shape, facilitating modular assembly and system-level integration.
Its core structural features include:
Highly consistent casing size control, ensuring precision in cell stacking and automated assembly.
Uniform wall thickness distribution design, avoiding localized stress concentration.
Flat inner walls and stable straightness, beneficial for electrode assembly and separator safety.
Customizable opening and flange structures, adaptable to different packaging and welding solutions.
This type of aluminum casing in the battery cell possesses dual attributes as both a structural and functional component, serving as a fundamental unit for achieving lightweight and high reliability in batteries.

AL3003-H14 (Main Choice)
Excellent formability, moderate strength, and good corrosion resistance. The best choice for balancing cost, performance, and processability, widely used in power batteries and energy storage batteries.
AL1060 (Purity Choice)
Extremely high purity gives lithium power cell an Aluminum shell excellent electrical and thermal conductivity and excellent ductility. Suitable for high-performance batteries with special requirements for heat dissipation and precise formability.
AL5052/AL6061 (Strength Choice)
A high-strength aluminum alloy with higher yield strength and fatigue resistance. Suitable for top-tier electric vehicle battery packs with extreme requirements for structural strength and crash safety.
Technical Features
Deep-Drawing Metal Flow: This is the core technology in manufacturing Aluminum shell for lithium iron phosphate prismatic cells. Through CAE simulation analysis, we precisely calculate the deformation, stretching speed, and lubrication conditions for each stretching process, guiding the metal material to flow smoothly within the mold, avoiding wrinkling and cracking, and achieving the ultimate depth-to-width ratio.
Laser Welding Metallurgical Bond: We employ a precision laser welding process to create a strong metallurgical bond between the Aluminum shell for single cell lithium ion battery and the cover plate. The weld's airtightness, strength, and aesthetics reach industry-leading levels, providing a sealing guarantee for the long-term safe operation of the battery.
Surface Treatment and Insulation Technology: We offer various surface treatment processes, such as anodizing and electrophoretic coating. This not only enhances the Prismatic Cell for BYD brand's corrosion resistance but also forms a dense insulating film on its surface, providing double protection for the battery's electrical safety.
Application Advantages: Meeting Cutting-Edge Technology Needs
Electric Vehicle Power Batteries
These require extremely high energy density, power density, and safety. Our lightweight Aluminum deep drawing stamping battery case design (e.g., using 5052 or optimized wall thickness 3003) and superior thermal interface performance directly contribute to improved vehicle range and fast charging capabilities. Their high strength and vibration resistance ensure reliability throughout the vehicle's lifespan.
Home and Commercial Energy Storage Systems
These require a cycle life and calendar life of 10-20 years. Our pursuit of material corrosion resistance and LiFePo4 LFP Lithium Iron Phosphate battery cells sealing reliability ensures long-term stable operation of the battery in complex temperature and humidity environments, reducing the levelized cost of electricity (LCOE) over the system's entire lifespan.
Power Tools and Drones
These require high-rate discharge and extremely high shock resistance. Our high-strength materials (e.g., 6061) or reinforced structural designs can withstand frequent acceleration shocks and internal pressure shocks from high-rate discharge, ensuring the performance and safety of equipment under harsh operating conditions.
High-End Consumer Electronics
Safety cannot be sacrificed while pursuing ultra-thin and irregularly shaped designs. We can produce ultra-thin, high-precision, irregularly shaped housings, ensuring their sealing and strength to meet the stringent space and safety requirements of top-tier electronic EV Battery Pouch Cell Aluminum Cases.
