Cemented Carbide Round Industrial Cutting Circular Slitting Blade For Lithium Battery
The parts in the battery industry are relatively precise, so the requirements for blades are relatively high. Lithium battery slitting cutter has good wear resistance and high machining accuracy, and its excircle accuracy is high. The lithium battery cutting blade has a spiral structure inside, and the positive and negative electrodes are separated by a layer of thin film paper with many tiny holes. The reaction mechanism of lithium battery cutting blade is that with the progress of charging and discharging, lithium ions are embedded and removed between the positive and negative electrodes, shuttling back and forth inside the cell without the existence of metal lithium, so the lithium ion cell is more safe and stable. The positive pole of lithium-ion battery adopts lithium cobalt oxide, and the positive current collector is aluminum foil; The negative electrode adopts carbon, the negative collector is copper foil, and the electrolyte of the lithium battery cutting blade is an organism that dissolves LiPF6.

Production process of lithium battery slitting blade:
1. Pulping: special solvents and binders are used to mix with powdered positive and negative active substances respectively. After high-speed mixing, the paste like positive and negative substances are made.
2. coating: evenly coat the prepared slurry on the surface of the metal foil, dry it, and make positive and negative plates respectively.
3. Assembly: put it in the order of positive plate diaphragm negative plate diaphragm from top to bottom, support the battery pole core by winding, and then inject electrolyte, seal and other processes, that is, complete the assembly process of the battery, and make the finished battery.
4. Formation: charge and discharge test the finished battery with special battery charging and discharging equipment, test each lithium battery, and select qualified finished batteries to be delivered.
Matters needing attention:
The lithium battery slitting blade is very sharp. Once the equipment is started, any material will be cut off instantly. Therefore, every operator is required to keep a high spirit at all times when carrying out the operation. Every feeding should keep his hand away from the slitting blade. He needs to be highly vigilant when carrying out the pressing device to prevent the possibility of being scratched by the blade.
