Lithium battery manufacturing process -Lithium - Ion Battery Equipment
General process of lithium-ion battery manufacturing
The basic principle of lithium battery is redox reaction. The chemical properties of lithium metal are very active, which makes the processing, storage, use, and manufacturing process of lithium metal quite strict and complicated.(Lithium - Ion Battery Equipment)
1. Pulping: Mix positive and negative active substances with special solvent and rubber powder, stir evenly at high speed, and make pulp into positive and negative substances;
2. Coating: The slurry is evenly coated on the surface of the metal foil, and after drying, the positive and negative electrode sheets are respectively made;
3. Assembly:
(1) Place the positive plate diaphragm and the negative plate diaphragm in order from top to bottom, and wind the battery core;
(2) Through the process of injecting electrolyte, sealing and other processes, the battery assembly process is completed, and the finished battery is made.
4. Transformation: Use special battery charging and discharging equipment to conduct charge and discharge tests on finished batteries, test each battery, screen qualified finished batteries, and wait for delivery.
Lithium-ion batteries are generally non-rechargeable and contain metallic lithium, while lithium-ion batteries do not contain metallic lithium and can be recharged.
The higher the price of the lithium-ion battery, the stronger the performance should be, and the performance generally refers to the performance of the capacitor on the carbon foil, there are about six kinds.
1. Suppress battery polarization, reduce thermal effects, and improve multiplier performance;
2. Reduce the internal resistance of the battery and significantly reduce the dynamic increase of the internal resistance during the cycle;
3. Improve consistency and prolong battery life;
4. Improve the adhesion between the active material and the collecting liquid, and reduce the manufacturing cost of the pole piece;
5. Protect the collected liquid from corrosion by the electrolyte;
6. Improve the high and low temperature performance of lithium iron phosphate batteries, and improve the processing performance of lithium iron phosphate and lithium titanate materials.
The carbon-coated aluminum foil for electric bicycle lithium-ion battery is based on conductive carbon and high-purity electronic aluminum foil. The composite paste made by the transfer coating process can significantly improve the comprehensive performance of lithium-ion batteries and capacitors.
