Technology Upgrade of New Energy Battery Structural Components: Multiple Components Collaborate to Strengthen Safety and Efficiency

Driven by the dual forces of new energy vehicles and the energy storage industry, battery structural components are experiencing a peak in technological iteration. Core components such as battery trays, end plates, and aluminum barrels are crucial for improving battery performance.

Battery trays, as the core load-bearing structure, are made of aluminum alloy, accounting for over 85%. They utilize a high-pressure die-casting process to achieve a balance between lightweight and high strength. Global demand is expected to exceed 42 million units by 2025. End plate technologies are showing diverging trends: extruded end plates offer flexible adaptability for diverse installation scenarios, while die-cast end plates enhance impact resistance through their integrated structure. Both utilize the high thermal conductivity of aluminum-based materials to optimize heat dissipation efficiency and reduce the risk of thermal runaway.

The aluminum barrel, a key component of battery cell packaging, utilizes 3003 aluminum alloy as its core material, achieving a 40% weight reduction while enhancing corrosion resistance. The accompanying cell tie design features a uniform force distribution, effectively absorbing vibration and shock, ensuring cell stacking stability.

Currently, these structural components are widely used in passenger vehicles, energy storage power stations, and other fields. Driven by both policies and the market, they are accelerating their evolution toward integration and greening.
