The Breakthrough for Lithium Battery Cost Reduction and Quality Improvement
2025-10-31
- •
Tooling Change Cost plummets by 99%from ¥50,000; no mold changes needed, simply adjust parameters to adapt to tab lengths of 70-150mm (including tabs) and widths of 50-120mm, enabling flexible switching between multiple specifications. - •
Laser usage cost is only ~¥5,000/year, equivalent to a single machine "earning an extra ¥580,000" annually for the company. The ROI period shortens to about 8 months, significantly faster than the 2+ years for traditional equipment.
- •
Cutting precision ≤15μm, Heat Affect Zone (HAZ) ≤100μm, Burrs ≤15μm(far below the national standard of 50μm), Spatter ≤15μm, and tab dimensional tolerance of ±0.1mm, eliminating thermal runaway risks from burrs at the source. - •
Proprietary PSO dynamic cutting compensation technologyadjusts laser power and overlap in real-time, ensuring consistent cut quality even at high speeds of 150 PPM or during low-speed debugging, increasing battery cycle life by 15%with capacity retention >85% after 2000 cycles.
- •
From dual unwind stands (max. roll diameter 700mm, automatic alarm for change), intelligent tension control, to laser processing, CCD dimension/flaw detection (misjudgment rate ≤0.3%), and automatic rejection of defective products, it achieves unmanned operation from "unwinding - cutting - inspection - winding". - •
Pre-equipped with MES communication interfacesenables seamless integration with smart management systems. Equipment operational rate ≥98%; product yield rate ≥99.5%, easily meeting high-volume production demands.
- •
Source Control:Air shafts for unwinding prevent friction; dust-proof devices for splicing minimize generation at the root. - •
Internal Purification:Built-in FFU HEPA filtration system maintains a Class 100,000clean environment inside the machine. Combined with powerful suction and sealed design, it prevents dust leakage. - •
Surface Cleaning:Dual cleaning with a soft brush and high-speed air knife ensures no residue on tab surfaces. - •
Real-time Monitoring:Dust sensors linked to alarms, with data synced to the MES system, ensuring compliance and safety.
