Product Description

Tungsten Carbide Blades for Lithium Battery Separator Cutting

Overview: The Tungsten carbide blades for lithium battery separator cutting are specialized equipment designed for the production process of lithium battery separators. Crafted from high-precision Tungsten carbide material, these blades consist of an upper disc-shaped blade with specifications φ98*φ66*0.7 and a lower rewind machine bottom blade with specifications φ80*φ55*9.5 or 10. The quality of these blades directly influences the operational quality of lithium battery separator cutting.
Key Features:

1. High Precision Material: Crafted from Tungsten carbide, both the disc-shaped upper blade and the rewind machine bottom blade undergo precision processing, ensuring that there are no gaps when magnified 150-200 times, thereby guaranteeing production efficiency and cutting quality.
2. Specialized Design: Tailored to the requirements of the lithium battery separator production process, the blade specifications are carefully designed to meet the high demands of lithium battery separator cutting.
3. Critical Role: The blades play a crucial role in the lithium battery separator cutting machine, directly impacting the final quality of the separator, including interface structure, internal resistance, and other properties, thereby affecting the battery's energy density, cycle life, and rate performance.

Application Areas: Suitable for the cutting process in the production of lithium battery separators, ensuring the production of thin film materials that meet high standards.
Considerations:

1. Ensure the cleanliness of the blade surface before use to avoid unnecessary impact on separator materials.
2. Regularly inspect the wear and tear of the blades and replace them promptly to ensure effective cutting.

Conclusion: Tungsten carbide cutting blades are crucial components in the lithium battery separator cutting process. Their high-precision design and specialized specifications ensure the requirements of production efficiency and cutting quality. Excellent blade quality contributes to the overall performance improvement of lithium batteries, ensuring their safety and stability.
