According to the production processes of lithium batteries, lithium tools can be divided into three major categories, which accurately match different processing scenarios and form a full-process solution.
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 battery cells
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 stacked battery cells, and uses special materials to reduce pollution and improve the quality of battery cells.
⏬Mainstream types: tab punching die, polytetrafluoroethylene composite cutter set. The die is specially treated to ensure no deformation.
⏬Core application: lithium battery cutting and stacking integrated machine, with a single service life of over 1 million times and supporting mold repair more than 10 times.
3. Cutting tools for battery pack structural parts processing
It is used for milling and drilling of structural components such as battery pack shells and water-cooled plates. It balances efficiency and precision, ensures the lightweight and sealing performance of the battery pack, and is suitable for materials such as 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 with traditional tools.
