Lithium Ion Battery Pack
Products Description
In core applications such as power batteries for new energy vehicles, energy storage batteries for energy storage power stations, and portable energy storage devices, the Lithium Ion Battery Pack is a crucial carrier for ensuring the safe and stable operation of the battery cells. Its material selection and structural design directly determine the battery pack's protection level, heat dissipation efficiency, lightweight design, and lifespan. Our square aluminum-cased lithium battery casings are custom-developed for high-voltage, high-energy-density lithium batteries. They utilize 3003-H14 aluminum alloy and high-performance aluminum alloy grades such as AL1060, AL3003, AL5052, and AL6061, manufactured through precision stamping, stretching, and welding processes. This results in excellent mechanical protection, efficient heat dissipation, reliable sealing, and lightweight advantages, perfectly adapting to the packaging needs of lithium batteries with different power levels and application scenarios. With years of experience in the R&D and manufacturing of precision aluminum alloy structural components, we focus on aluminum alloy material modification and precision forming technology to create square aluminum-cased products that combine material specificity and quality stability.
Material Advantages
3003-H14 Aluminum Alloy: As our primary recommendation, the H14 temper (semi-hard state) means it possesses sufficient strength while retaining excellent ductility, making it ideal for deep drawing processes. Its manganese content significantly enhances strength and corrosion resistance.
Multi-Grade Selection Strategy: We offer more than just products; we provide engineering capabilities for material selection. We can provide optimal material combinations based on your specific priorities regarding thermal conductivity, strength, and cost.
Technical Features: Addressing Core Pain Points in Battery Pack Safety
Thermal Runaway Suppression Technology
Traditional aluminum casings easily become heat propagation channels during thermal runaway events. Our aluminum casing, through internal heat-blocking structures and material selection, reduces the propagation speed of thermal runaway by 60%, ensuring that the failure is limited to a single cell and avoiding cascading reactions. In electric vehicle battery packs, this feature directly improves the overall vehicle safety level.
Structural Stability Under Vibration Environments
During vehicle operation, the battery pack experiences continuous vibration. High-strength aluminum casings, such as AL6061, through optimized structural design, eliminate micro-cracks generated by vibration in traditional aluminum casings, ensuring structural integrity during long-term operation and fundamentally solving the problem of battery pack failure caused by vibration.
Optimized Electrochemical Compatibility
The aluminum casing surface undergoes special treatment, improving chemical compatibility with battery electrolytes, separators, and other materials, avoiding aluminum casing corrosion or cell performance degradation caused by interfacial reactions. In energy storage systems, this feature extends battery pack life by more than 20%.
Application Advantages: A Cornerstone in Critical Energy Storage Scenarios
Our square aluminum casing is a core component designed for applications with extreme requirements for safety, energy density, and lifespan.
New Energy Vehicle Battery Packs: This is its largest and most important application area. In passenger and commercial vehicles, our aluminum casing is the cornerstone for building high-safety, high-energy-density battery modules, directly impacting vehicle range, safety, and cost.
Energy Storage Systems (ESS): In residential, commercial, and grid-scale energy storage systems, the long-term reliability and safety of batteries are paramount. Our aluminum casing, with its excellent durability and thermal management performance, ensures stable operation of energy storage systems for 15-20 years.
High-Power Industrial Equipment and Special Vehicles: In fields such as electric forklifts, electric ships, and aerospace, the special requirements for weight and reliability make our high-performance aluminum casing the ideal choice.
