What are the essentials of lithium battery processing?

1. The treatment of the negative electrode material must first evacuate the large particle size and ultra-fine powder from the required particle size to prevent chemical reverberation and improve the safety of the battery cell. The method of improving the porosity of the material appearance can increase the capacity by more than 10%. At the same time, the safety performance of the lithium-ion battery can also be improved in an environment with a stable C/A ratio. 2. The control of the pulping process The pulping process generally uses extraordinary chemical reagents to minimize the tension between the positive and negative slurry. Improve the compatibility between the groups and prevent the agglomeration of materials during the mixing process. During coating, the open area between the substrate material and the nozzle should be kept below 0.2mm, so that the surface of the formed plate is smooth and free of defects such as particles, dents, scratches, etc. The storage time of the slurry is maintained at more than 6 hours, and it is guaranteed that there is no self-agglomeration inside the slurry. The well-proportioned slurry is the uniformity of the diffusion on the base material of the positive and negative electrodes of the lithium ion battery, which improves the consistency of the battery cell. 3. Recycling advanced pole piece manufacturing equipment. Advanced equipment not only guarantees the quality of the pole piece, but also greatly improves the uniformity of the cell pole piece and improves the passing rate of the cell. The density error value on the single plate of the coating machine should be kept within a certain range.
