After years of development, the lithium battery industry has formed a complete industrial chain with a high degree of specialization. Do you know how the lithium battery is made? The following is a brief introduction to the production process of lithium batteries : 1. Chemicals preparation. The electrode active material, binder, solvent, etc. are mixed together, fully stirred and dispersed to prepare a slurry. 2. Coating. The slurry is intermittently and evenly coated on the surface of the conveying current collector and dried to form a pole piece roll of positive and negative electrodes, respectively. 3. Cold press. After the positive and negative electrode plates are coated, the positive and negative materials are relatively sparse, and a certain pressure needs to be given to the pole pieces to compact the positive and negative electrode materials to a certain range. 4. Cut into pieces. According to the size of battery, the positive and negative electr...
