Bettery Cover Plate
Products Description
The Battery Cover Plate is a critical component engineered for new energy battery applications, especially in electric vehicle (EV) battery packs and energy storage systems. It is crafted from a high-strength aluminum alloy (aluminum content ≥95%) for the main plate, copper alloy (copper content ≥99%) for metal knobs, and engineering plastics (e.g., PA66) for plastic components. This Lithium Battery Top Cap material combination ensures structural integrity, electrical conductivity, and durability.
For surface treatment, the aluminum alloy plate undergoes anodic oxidation (thickness ≥8μm) for enhanced corrosion resistance, while metal knobs feature gold or silver plating (thickness ≥5μm) to boost conductivity and aesthetic appeal. Plastic components undergo precision injection molding without additional special treatments. In terms of application, the Battery Aluminum Safety Cover Set serves as a vital element for battery sealing, electrical connection, and functional operation in new energy lithium batteries and EV battery modules.
Manufacturing Process
Aluminum Alloy Plate Processing
The production of the aluminum alloy plate involves cutting (dimensional accuracy ±0.1mm), stamping (precision ±0.05mm), drilling (hole diameter accuracy ±0.02mm), and anodic oxidation. This process ensures the plate meets strict dimensional and corrosion-resistant standards, making the Aluminum Cover Plate for Batteries suitable for harsh battery environments.
01
Metal Knob Production
Metal knobs go through machining (dimensional accuracy ±0.03mm), plating (thickness 5-10μm), and assembly. The precise machining and plating guarantee excellent electrical performance and longevity, which is crucial for the Prismatic Lithium Battery Canopy's operational reliability.
02
Plastic Component Manufacturing
Plastic components are produced via injection molding (dimensional accuracy ±0.05mm) followed by assembly. This process ensures the components fit seamlessly with other parts of the top lid for prismatic battery cell, contributing to the overall product integrity.
03
Final Assembly
The final assembly of the copper and aluminum bimetal bipolar plate is done either manually or semi-automatically, with an assembly accuracy of ±0.1mm. This precise assembly ensures all components work harmoniously, delivering consistent performance.
