Introduction of lithium battery slitter blades

The parts in the battery industry are relatively precise, so the requirements for blades are relatively high. The lithium battery slitter has good wear resistance and high machining accuracy, and the outer circle accuracy of the tool is high. The inside of the lithium battery slitting blade has a spiral structure, and the positive electrode and the negative electrode are separated by a layer of thin film paper with many tiny pores. The reaction mechanism of the lithium battery slitting blade is that with the progress of charging and discharging, lithium ions are inserted and extracted between the positive and negative electrodes, and shuttle back and forth inside the battery without the existence of metal lithium, so the lithium ion battery is more secure and stable. The positive electrode of the lithium ion battery is lithium cobalt oxide, the positive electrode current collector is aluminum foil; the negative electrode is carbon, the negative electrode current collector is copper foil, and the electrolyte of the lithium battery cutting blade is an organic body that dissolves LiPF6.

Production process of lithium battery slitting blade:

1. Slurrying: Mix the powdered positive and negative active materials with special solvents and binders, and stir them evenly at a high speed to make slurry positive and negative materials.

2 Coating film: The prepared slurry is evenly coated on the surface of the metal foil, dried, and made into positive and negative pole pieces respectively.

3. Assembly: Place the positive electrode sheet-diaphragm-negative electrode sheet-diaphragm in the top-down order, and support the battery pole core by winding, and then through the process of injecting electrolyte and sealing, the assembly process of the battery is completed. , made into the finished battery.

4. Formation: use special battery charging and discharging equipment to conduct charge and discharge tests on finished batteries, test each lithium battery, and screen out qualified finished batteries before leaving the factory.

Precautions:

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 maintain a high degree of spirit when working, and every feeding must be cut. When the hand is away from the slitting blade, a high degree of vigilance is required when carrying out the pressing device to prevent the possibility of being scratched by the blade.
