Battery Shell: Core Manufacturing Carrier in The Lightweight Era

Amid the lightweight and green transformation of manufacturing, Battery Shell has become an indispensable core component in electronic equipment, new energy vehicles, aerospace and other fields, relying on advantages such as light weight, high strength and excellent thermal conductivity. With diverse forms and reliable performance, it supports the operation of core equipment and drives industrial upgrading. Benefiting from the expansion of downstream markets and technological iteration, the Automotive Battery Aluminum Case industry is entering a new development stage.

Aluminum Case for New Energy Cars stands out due to its multi-scenario adaptive characteristics. First, its light weight and high strength reduce end-product weight while ensuring stability, making it preferred in automotive lightweight and aerospace. Second, excellent thermal conductivity solves heat dissipation issues and extends product life. Third, good corrosion resistance (enhanced by anodizing) adapts to complex environments. Additionally, its high plasticity enables customized production via extrusion, die casting and other processes.

Lithium Battery Aluminum Case has diversified processing technologies, with mainstream types matching different application scenarios as follows:

• Extrusion-molded type: High efficiency and consistency - Suitable for long-strip or complex-section Battery Aluminum Cases, with high production efficiency. Widely used in electronic equipment frames and automotive profiles, accounting for 65.2% of the market.
• Die-cast type: High precision for mass production - Suitable for complex and thin-walled New Energy Aluminum Battery Cases, with fast production speed. Mainly used in new energy vehicle power batteries, accounting for 24.8% of the market.
• CNC precision-machined type: High precision for high-end fields - With precision up to ±0.01mm, suitable for complex curved Aluminum Battery Casing. Applied in high-end electronics and aerospace, relying on CNC technology for performance guarantee.
• Coated type: Insulation and explosion-proof - Coated with insulating film, available in various types. Mainly used in electronic components, meeting strict industry standards for safe use.

The Battery Shell industry is evolving towards high-end, green and intelligent directions, while facing challenges such as raw material price fluctuations. Trends include mature integrated die-casting, increased use of aluminum-magnesium alloy and popularized intelligent production. Challenges lie in electrolytic aluminum price volatility, EU carbon tariff pressure and equipment renewal costs for SMEs.
