Product Description Product DescriptionWith the development of microelectronics technology development, miniaturized devices are increasing day by day, which puts high demands on power supplies. Lithium batteries have become an indispensable part of digital products. The electrode sheet is one of the core components of the lithium battery. The electrode sheet is generally cut from metal foil, copper foil. Tungsten steel lithium battery blades used in lithium battery manufacturing industry, the positive and negative pole of lithium battery slitting process, racked in pole pieces of the unit.Tungsten carbide circular blades used in the battery industry have specialized characteristics that make them ideal for high-precision cutting, shaping, and processing of battery components, such as electrodes, separator films, and casings. These blades are engineered to withstand the demanding conditions typical of battery production. Here are the key characteristics of tungsten carbide circular blades for the battery industryThe cutting process of aluminum foil should be very precise, because any burr on the aluminum foil may cause a short circuit of the lithium battery. And to achieve such precise cutting requires sharp and wear-resistant tungsten carbide battery knives.1. Our specialized equipment enables us to manufacture discs from 40mm to 300mm in diameter with a thickness range of 0.25mm to 5mm.2. Our Cutting Knives and Discs can be supplied with either a standard ground or highly polished cutting edge depending on the material to be cut and/or the lifetime required of the tool.3. Our dedicated team of technical project managers are all highly qualified and experienced. We can help to develop the cutting profile and product best suited to your needs.4. Our careful selection of materials the life of existing knives can be extended to reduce the downtime of tooling changes.Partial models with specification as below table: DescriptionDimensionBlade AngleSlitting Top Blade?100×?65×0.726°, 30°, 35°, 45°Slitting Bottom Blade?100×?65×226°, 30°, 35°, 45°, 90°Slitting Top Blade?100×?65×130°Slitting Bottom Blade?100×?65×390°Slitting Top Blade?110×?90×126°, 30°Slitting Bottom Blade?110×?75×390°Slitting Bottom Blade?110×?90×390°Slitting Top Blade?130×?88×126°, 30°, 45°, 90°Slitting Bottom Blade?130×?70×3/590°Slitting Top Blade?130×?97×0.8/126°, 30°, 35°, 45°Slitting Bottom Blade?130×?95×4/526°, 30°, 35°, 45°, 90°Slitting Top Blade?98×?66×0.7/0.830°, 45°, 60°Slitting Bottom Blade?80×?55×5/103°, 5°Slitting Top Blade?110×?90×126°, 30° This blade with very high precision requirement, the material must be the original raw material sub-micron tungsten carbide grains, cutting edge generally 200-500 times magnification detection required without gaps.Large surface grinding technology to achieve the mirror effect finish Ra less than 0.02. Sharp cutting edge without burrs, cutting force to ensure battery pole piece product quality.Cutting edge types: Single or double side availableTungsten carbide grade:The components of tungsten carbide are WC(hard phase) and cobalt (binder phase).The physical properties of alloy depend on the grain size of WC and the percentage of hard phase,we have dozens of material grades for your different applications.

The blades allow for highly accurate cuts without damaging the electrode.Separators and Films: Tungsten carbide circular blades are ideal for cutting separator films used between the anode and cathode in lithium-ion batteries. The films are often made of materials like polyethylene (PE) or polypropylene (PP), which require clean, precise cuts.Battery Casings: In some cases, tungsten carbide circular blades are used for cutting or trimming battery casings or other structural components, ensuring a clean edge and smooth finish.Slitting Battery Components: Tungsten carbide blades are used for slitting large rolls of battery materials, including electrode sheets and separators, into smaller, more manageable sizes for further processing.Laser and Laser-cutting Preparation: These blades are sometimes used in preparation for laser-cutting operations on certain battery components, ensuring that edges are clean and consistent before the more intricate laser cutting takes place. Our AdvantagesHigh hardness and long edge retention for precise, sharp cuts.Exceptional wear resistance and durability, ideal for high-volume applications.Corrosion resistance to withstand harsh processing conditions.Temperature resistance for stable performance at elevated temperatures.Precision for clean, accurate cuts, which are critical in battery component production.Long tool life with minimal maintenance, reducing downtime and costs.Packing and delivery:1.
