Driven by both the global technological revolution and the "dual carbon" goals, the automotive industry is accelerating its transition to electrification, and the new energy vehicle (NEV) market maintains a strong growth momentum. As a core component of NEVs, the manufacturing process and quality of power batteries directly affect the performance and safety of the entire vehicle. To meet the industry's demand for high-standard and large-scale air supply, we rely on clean, stable, and efficient compressed air to fully empower battery manufacturers to improve production yield, implement intelligent manufacturing, and achieve high-quality capacity expansion.

Why Is High-Quality Compressed Air Critical for Battery Manufacturing?

As the core power source for driving and controlling production equipment, compressed air is widely used in all key processes throughout the battery manufacturing workflow:

-Slurry Mixing: Provides power for vacuum mixers to ensure uniform mixing of positive and negative electrode slurries, guaranteeing the dispersibility of active materials;

-Electrode Sheet Manufacturing: Supplies a stable air source for positive/negative electrode coating machines, ensuring uniform coating thickness and strong adhesion;

-Forming & Processing: Assists roll presses in achieving precise compaction of electrode sheets, and supports slitting machines, cutting machines, and punching machines to complete electrode sheet forming;

-Cell Assembly: Drives winding machines, welding machines, sealing equipment, and injection molding machines to realize cell winding, tab welding, and sealing;

-Post-Processing: Provides power for formation equipment, ensuring stability during the cell activation process;

-Finished Product Packaging: Empowers automatic/semiautomatic assembly lines to complete the packaging and testing of battery modules and Packs.

Battery production has extremely strict requirements for air source quality: even trace contaminants can lead to degraded battery performance, shortened service life, or even pose safety hazards. Therefore, compressed air must meet ultra-high purity standards—achieving absolute oil-free operation, ultra-low moisture content, and zero dust particles.

Benchmark Case

A battery manufacturer in Xi'an has set extremely high requirements for the air compressor system of its new production line: it not only needs to achieve large-scale, continuous, and stable air supply but also requires the air source quality to reach industry-leading levels to ensure high yield and safety reliability in battery production. If the air source quality fails to meet standards or the supply is interrupted, it will cause significant economic losses.

To address this demand, the air compressor system solution includes the following core components:

-Core Configuration: 5 high-power centrifugal air compressors (responsible for continuous and stable air output), paired with 2 dry oil-free variable-frequency screw air compressors (to cope with air volume fluctuations and achieve precise flow control). The centrifugal air compressors and oil-free screw air compressors work in synergy to fully meet the production air demand;

-Intelligent Control Strategy: The coordinated operation of centrifugal units (running at constant pressure) and variable-frequency screw air compressors (for precise flow regulation) enables efficient response to load changes and significantly improves the overall energy efficiency of the system;

-Waste Heat Recovery: Integrated waste heat recovery modules realize cascaded utilization of thermal energy, greatly improving the comprehensive energy utilization rate and further reducing operating costs.

This system has established a centralized air supply system with high stability, high efficiency, and high cleanliness, fully meeting the strict requirements for compressed air in key processes such as electrode sheet manufacturing and cell assembly.
