InquiryHENGLIDA High-Precision Lithium Battery Electrode Slitting Blades
Ultra-Fine Tungsten Steel · Nano-Level Grinding · Ultra-Long Service Life of 80,000 to 300,000 Meters
With over 20 years of experience in R&D and precision manufacturing of industrial blades, HENGLIDA develops high-precision circular slitting blades exclusively for lithium battery electrodes in the new energy sector. We adopt top-tier ultra-fine grain cemented carbide (tungsten carbide) paired with rigorous constant-temperature inspection processes, ensuring exceptional dimensional stability and consistent cutting edge sharpness during high-speed slitting. The blades effectively eliminate common defects including powder shedding, burrs and wavy edges on electrode sheets.
I. Core Technical Advantages
1. Premium Ultra-Fine Grain Tungsten Carbide
Our blades are sintered from ultra-fine nano-grade tungsten carbide powder, delivering superior hardness and outstanding wear resistance.
Applicable Electrode Materials: Ideal for high-speed slitting of hard and adhesive electrode materials such as Lithium Iron Phosphate (LFP), Ternary Materials, Lithium Manganese Oxide (LMO) and Lithium Cobalt Oxide (LCO).
Ultra-Long Service Life: Depending on slitting materials and processes, the service life per grinding reaches 80,000–300,000 meters, drastically reducing blade replacement frequency and downtime maintenance costs.
2. Military-Grade Precision Manufacturing Tolerances
To satisfy the lithium battery industry’s stringent dimensional requirements for electrode sheets, HENGLIDA conducts precision grinding and high-accuracy inspection in constant-temperature workshops:
Thickness Tolerance: Strictly controlled within ±0.001 mm to minimize cumulative axial errors during multi-blade combined slitting.
Surface Roughness: Mirror finish up to Ra 0.1μm lowers slitting resistance and effectively prevents material adhesion.
Inner Bore Tolerance: Complies with ultra-high precision H3 standard, minimizing radial runout at high rotating speeds for ultra-smooth cut edges.
II. Excellent Compatibility with Mainstream Slitting Equipment
HENGLIDA lithium battery slitting blades feature outstanding assembly compatibility and can perfectly replace original imported blades. Compatible with mainstream lithium battery slitter brands including Nishimura, YAKANG, Lange, Haocanying, Maxima (Sharp), Dudley, etc.
