Aluminum Deep Drawing Stamping Battery Case
Products Description
The Aluminum deep drawing stamping battery case is integrally formed using a deep-drawing stamping process, resulting in a seamless or minimally jointed structure with inherent mechanical continuity. Compared to traditional assembled structures, the deep-drawn casing offers greater predictability in terms of stress path, deformation uniformity, and fatigue life.
Key structural design features include:
Balanced control of wall thickness distribution
Stress optimization in rounded corner transition areas
Coordinated overall rigidity between the bottom and sidewalls
Mass production stability of dimensional tolerances
This type of structure is naturally suited for high-energy-density cell layouts, directly impacting cell stacking stability and module assembly accuracy.
Technical Features: Deep Integration of Process and Materials
Technically, this Aluminum Battery Box emphasizes three key characteristics: precision, controllability, and compatibility. During deep drawing, the aluminum alloy grains undergo directional rearrangement and work hardening, significantly improving yield strength and fatigue limit while maintaining excellent ductility to support larger aspect ratio designs. Surface micro-treatment technologies include anodizing combined with nano-functional coatings, enhancing resistance to electrolyte corrosion while providing additional insulation or radiative heat dissipation. The LiFePO4 Aluminum Case Battery Cell is highly compatible with downstream processes such as laser welding, ultrasonic cleaning, and BMS sensor embedding, with flange surface flatness and roughness controlled within the optimal window for laser sealing. The engineering simulation team used finite element analysis during the design phase to verify thermo-mechanical coupling behavior, ensuring the housing remains stable across a wide temperature range of -40℃ to 85℃. These technical features make each housing a quantifiable engineering asset, rather than a simple standard part.
Application Advantages: Full-Scenario Coverage
New Energy Vehicle Power Batteries
As the standard packaging form for passenger vehicle power battery packs, our square aluminum shell perfectly adapts to various chemical systems such as high-nickel ternary and lithium iron phosphate (LFP) cells. Its high structural strength helps improve the overall torsional rigidity of the battery pack, meeting the ASIL-D functional safety level requirements for mechanical strength.
Energy Storage Systems
In containerized energy storage power stations and home energy storage systems, the excellent weather resistance and thermal conductivity of the aluminum shell support the stability of battery modules under long-life, high-load operation. Its lightweight characteristics also reduce the foundation and installation costs of large-scale energy storage projects.
Industrial Equipment and Drones
For the extreme weight sensitivity of industrial mobile equipment and drones, our EV Battery Pouch Cell Aluminum Case provides an optimal energy density ratio solution, ensuring a balance between range and durability.
