Product Introduction
Products Description
As a key component of the Aluminum shell for lithium ferro phosphate cell structure system, the aluminum shell not only protects and stabilizes the internal pole piece group but is also directly related to the safety, energy density, heat dissipation efficiency, and overall performance of the battery cell. The lithium iron phosphate-specific aluminum shell products we provide are widely used in power batteries, energy storage systems, two-wheeled vehicle batteries, ship/communication energy storage, industrial backup power supply, and other fields, combining strength, dimensional accuracy, electrochemical stability, and customization capabilities.
Core manufacturing advantages
Ultra-high heat dissipation efficiency
Adopting 6061-T6 aluminum alloy, the thermal conductivity is 201 W/(m·K), which is more than 3 times higher than the traditional steel shell, effectively reducing the operating temperature of the battery pack by 5~8℃.
01
Lightweight design
Adopting aviation-grade aluminum alloy die-casting, the density is only 2.7g/cm³, which is 35% lighter than the steel shell, helping to reduce the overall weight of the battery pack by 10%~15%.
02
IP67 protection level
Laser welding + elastic sealing ring double protection, passed IP67 certification (IEC 60529 standard), can withstand 1 meter deep water immersion for 24 hours and high-pressure spray test.
03
High mechanical strength
6061-T6 aluminum alloy tensile strength ≥ 290MPa, yield strength ≥ 240MPa, bending strength ≥ 270MPa (ASTM B557 standard), can withstand battery pack stacking and vibration impact.
04
Precision manufacturing tolerance
CNC five-axis linkage processing + three-coordinate detection is used, and the tolerance of key installation holes is controlled at ±0.05mm, and the flatness is ≤0.1mm/m.
05
The material has excellent performance, both thermal conductivity and corrosion resistance
Thermal conductivity
Thermal conductivity is a key indicator of thermal management of battery core aluminum Power Battery Shells, especially in high-rate charging and discharging and high-temperature environments, where heat dissipation efficiency directly affects the life and safety of the battery core.
Excellent corrosion resistance
The aluminum alloy we use has an optimized alloy ratio, has strong oxidation resistance and electrolyte corrosion resistance, and prevents white spots, blackening, blistering, and other failure problems in the Prismatic Cell Aluminum Battery Case during packaging and long-term operation.
High strength
The battery core aluminum Lithium-Ion Battery Pack in the PACK module not only plays a structural support and protection role, but also needs to withstand physical loads such as assembly stress and vibration shock.
Low-density design
Compared with steel shells or composite shells, the use of aluminum lithium cell battery Aluminum shells can reduce the overall weight by 20%~30%, especially in mobile energy scenarios such as electric vehicles, drones, and two-wheeled vehicles, directly improving the unit energy density and vehicle range.
