Lithium Knife

1. Special cutting tools for pole piece slitting

It is used for high-precision slitting of positive and negative electrode sheets as well as copper foil and aluminum foil substrates. The slitting quality directly affects the burr height of the electrode sheets and battery safety, and it is a core tool for electrode sheet preparation.

⏬Mainstream types: ultra-fine grain cemented carbide circular blades, upper and lower咬合式 slitting knife sets, with common specifications such as 100×65×0.7 pole piece upper knife, 130×70×3.0 lower knife.
⏬Core applications: compatible with mainstream slitting equipment, meeting the processing needs of high-energy density batteries.

2. Special cutting tools for cell cutting

For the punching of battery cell tabs and the cutting of their outer shapes, it solves the problems of material sticking and dust generation with traditional tools. It is suitable for the processing of laminated battery cells, and uses special materials to reduce pollution and improve the quality of battery cells.

⏬Mainstream types: tab punching dies, polytetrafluoroethylene composite cutter sets. The dies undergo special treatment to ensure no deformation.
⏬Core applications: lithium battery cutting and stacking integrated machines. The single service life exceeds 1 million times, and it supports more than 10 die repairs.

3. Cutting tools for battery pack structural parts processing

It is used for milling and drilling structural components such as battery pack casings and water-cooled plates, balancing efficiency and precision, ensuring the lightweight and sealing performance of battery packs, and is compatible with materials like aluminum alloys and carbon fibers.

⏬Mainstream types: nano-coated graphite milling cutters, special end mills for aluminum alloys, TiAlN coating enhances wear resistance.

⏬Core application: Adapted to CNC machining centers, with a metal removal rate increased by more than 250% compared to traditional tools
