3 Things About Tungsten Carbide Circular Blade For Cutting Lithium Battery

Published On: December 25, 2020

Carbide Lithium battery cutting bladesof Kone Carbide are made of ultra-fine-grained primary materials. product has good metallographic structure and high processing accuracy. excellent material selection and professional edge grinding technology achieve advantages of flat and sharp edges. resistance is small, wear resistance is high, blade is sharp and durable, and its life is more than 5 times that of high-speed steel, which effectively improvesproduction efficiency and has an unparalleled cost performance.


Cutting method of Tungsten carbide lithium battery blade


At present, there are two kinds of electrode slice making methods for lithium-ion power battery, which are blade cutting and laser cutting. edge burr of electrode piece is large, coating area is easy to be damaged, quality of electrode piece is difficult to guarantee and qualified rate is low. At present, laser cutting technology has been widely used. Because laser cutting is easy to cut any size and shape through program control, edge of electrode piece is free of burr and damage, and quality of electrode piece is easy to guarantee and qualified rate is high. However, laser cutting will produce high temperature, which will affect active substances in coating area, thus affecting performance of lithium batteries.

Working principle of Tungsten Carbide lithium batteryblade internal structure of blade is spiral, and cathode is separated by a layer of thin film paper with many tiny holes. Lithium ion cell is a new type of battery energy. It does not contain metal lithium. In process of charge and discharge, only lithiumion moves between positive and negative electrodes, and electrode and electrolyte do not participate in reaction. energy capacity density and weight capacity density of lithium battery slitting blade can reach 300wh / L and 125wh / L respectively. reaction mechanism of lithium battery slitting blade is that with charge and discharge process, lithium ion is embedded and separated between positive and negative electrodes, which shuttles back and forth inside cell without existence of metal lithium, so lithium-ion cell is more secure and stable. positive electrode of lithium-ion battery is lithium cobalt oxide, positive collector is aluminum foil; negative electrode is carbon, negative current collector is copper foil, and electrolyte of lithium battery slitting blade is organism dissolved LiPF6.


cathode material ofcarbide lithium battery slitterbladeis lithium cobalt oxide, and negative electrode is carbon. When lithium battery is charged, lithium ion is generated on positive electrode of lithium battery, and lithium ion of raw tea leaves moves to negative electrode through electrolyte. carbon as negative electrode presents a layered structure, which has many micropores. lithium ions that reach anode are embedded in micropores of carbon layer. more lithium ions are embedded, higher charging capacity. In same way, when party discharges battery (i.e. process of using battery), lithium ion embedded in negative carbon layer is released and moves back to positive electrode. more lithium ions returned topositive electrode, higher discharge capacity. What we usually call battery capacity is discharge capacity. There is an explosion-proof hole on cover cap of lithium-ion battery. When internal pressure is too high, explosion-proof hole will automatically open to relieve pressure to prevent explosion.

Production process of lithium battery slitting blade

  1. Pulping: mixing special solvent and binder with powder positive and negative active substances respectively, after high-speed stirring, paste like positive and negative electrode materials are made.
  2. coating film: slurry is evenly coated on surface of metal foil, dried, and made into positive and negative electrode plates respectively.
  3. Assembly: put battery in order of positive plate diaphragm negative plate diaphragm from top to bottom. After winding to supportbattery cell, and n through process of injecting electrolyte and sealing, battery assembly process is completed and finished battery is made.
  4. Into: use special battery charging and discharging equipment to test charging and discharging of finished battery. Every lithium battery is tested, and qualified finished battery is screened out for delivery.
