ETaC-3 Coated Carbide Slitting Knife for Li-ion Battery Electrodes
Detailed Description
For lithium-ion battery manufacturers demanding micron-level precision, Shen Gong Carbide Knives (SG) introduces the ETaC-3 coated slitting knife. Built to handle demanding production lines, our blade cuts battery electrodes at high speeds with near-zero burrs. The secret? We start with ultra-fine edge grinding, add durable PVD coating, and back it all with ISO 9001-certified quality control. Whether you're making EV batteries, 3C electronics, or energy storage systems, this blade delivers the consistent performance your operation needs.
Features
Built to Last – High-density tungsten carbide stands up to non-stop production, keeping your blades cutting sharper for longer.
Smooth Operator – Our PVD coating doesn’t just protect—it keeps friction low and stops metal gunk from sticking to your blade.
Surgical Precision – Edges so sharp they leave behind less than 5µm of burr, meaning cleaner cuts and better battery performance every time
Precision Lapping Technology – Ensures flatness within ±2µm for stable cuts.
Anti-Stick Grinding Process – Lowers contamination risk in NMC/LFP electrode slitting.
OEM Customization – Tailored dimensions, coatings, and edge geometries.

Applications
EV Batteries：Our blades slice through tough NMC and NCA cathode materials like butter - perfect for keeping up with fast-paced electric vehicle battery production lines. Whether you're working with nickel-rich formulations or ultra-thin foils, we've got the cutting solution that won't slow you down.
Energy Storage: When you're building grid-scale batteries with thick LFP electrodes, you need a blade that can handle serious material without compromising on cut quality. That's where our tungsten carbide toughness shines, delivering clean edges batch after batch for storage systems that last.
3C Batteries:3C batteries demand perfection - especially when working with delicate LCO foils thinner than a human hair. Our micron-level control means you get razor-sharp precision for smartphones, tablets and wearables where every micrometer matters.
Q&A
Q: Why choose SG’s ETaC-3 over standard blades?
A: Our PVD-coated carbide reduces wear by 40% vs. uncoated blades, critical for high-volume LFP production.
Q: Can you customize blade diameter/thickness?
A: Yes—SG offers OEM solutions for unique electrode widths (e.g., 90mm-130mm).
Q: How to minimize edge chipping?
A: The micro-grinding process strengthens the edge for 500,000+ cuts under optimal conditions.
