Lithium Cell Batteries Aluminum Shell
Products Description
In the current lithium battery system, where high energy density and high safety standards are developing in parallel, lithium cell batteries Aluminum shell are no longer simply "containers," but rather crucial functional parts directly involved in thermal management, mechanical protection, and system integration.
This square lithium battery's aluminum alloy casing is designed with engineering-grade applications in mind. It features dual structural and material optimizations for cell expansion control, thermal diffusion path optimization, and long-term cycle stability, meeting the stringent reliability and consistency requirements of power batteries and energy storage systems.
Materials Science Advantages: Customized Grades and Physicochemical Properties
3003-H14 Aluminum-Manganese Alloy
As the most widely used grade, it retains good formability while incorporating manganese to enhance tensile strength and corrosion resistance. The H14 temper ensures the stability of the casing during laser welding, making it the mainstream choice for prismatic battery cells.
AL1060 High-Purity Aluminum
Possesses excellent electrical and thermal conductivity, and extremely high ductility, suitable for ultra-deep drawing processes. Commonly used in small-capacity or high-power battery cells where weight is extremely sensitive.
AL5052 Aluminum-Magnesium Alloy
Offers higher fatigue strength and excellent resistance to seawater/atmospheric corrosion, suitable for energy storage devices in marine propulsion or extreme environments.
AL6061 reinforced alloy
After heat treatment, Customized Prismatic Battery Cell Casings have extremely high mechanical compressive strength and are suitable for special power supplies with extremely high requirements for structural explosion protection.
Core Production Processes: The Transformation from Sheet Metal to Precision Containers
| Precision Blanking and Lubrication Coating | High-precision continuous die blanking ensures burr-free edges; environmentally friendly special drawing oil is sprayed to ensure that the aluminum surface lattice is not damaged under extreme friction conditions. |
| Multi-Station Deep Drawing | For the characteristics of the Lithium-ion Battery Pack, a multi-stage drawing process (typically 3-5 draws) is used. Each draw is coordinated with specific die gaps and feed speeds, allowing the metal fibers to flow along a set path. |
| Intermediate Annealing | An online bright annealing furnace is inserted between key drawing processes to eliminate work hardening and restore the ductility and toughness of the aluminum alloy. This is a crucial process node to prevent orange peel and cracking in the finished LiFePO4 Battery Pack. |
| High-Precision Edge Trimming and Punching | Through robotic arm linkage, irregular flange edges after drawing are precisely trimmed, while simultaneously punching out pole mounting holes, ensuring the hole position relative to the reference plane reaches a ±0.05mm level. |
Design and Application Advantages: Cross-Industry Compatibility
Energy Density Optimization: The ultra-thin wall design reduces the volume ratio of the Aluminum Case for Electric Motor Car Lifepo4 Battery Pack while maintaining strength, leaving more space for active materials.
Modular Adaptability: Our square design supports compact modular stacking (Module-to-Pack), achieving extremely high space utilization with a liquid cooling system.
Comprehensive Application Coverage:
Passenger Vehicles/Buses: BEV/PHEV power battery modules.
Energy Storage Systems (ESS): Grid-side and commercial/industrial energy storage cabinets.
Heavy Machinery: Power battery packaging for mining trucks and forklifts.
