What are the issues that should be paid attention to in the lithium battery processing technology?

1. Improve the physical and chemical structure of the positive and negative active materials, which is the basic link of the lithium iron phosphate battery processing technology; 2. The high bonding strength of the electrode coating is beneficial to reduce the cycle capacity drop rate, which is the most important part of the lithium battery processing technology. Process with technical content; 3. Optimization of electrolyte composition. The requirement of lithium iron phosphate battery processing technology regarding electrolyte is to maintain capacity and extend the life of lithium battery; 4. After the preparation of lithium battery materials, the lithium battery processing technology enters the assembly At this time, it is necessary to pay attention to the gap between the positive and negative electrodes and the separator after winding the positive and negative electrodes and the separator. The particle size of the gap between the positive and negative electrodes and the separator is not more than 0.5mm, and the upper and lower deviations are not more than 0.5mm. 5. During the sub-capacity test, it is advisable to charge at a low rate in accordance with national standards, generally 0.2C. In general, lithium batteries should pay attention to the following proportional relations in the process and manufacturing stage: the compaction density of the pole piece surface and the pole piece, the excess rate of the negative electrode, the formulation process, and the appropriate amount of electrolyte and the positive and negative electrodes. Because the performance and endurance of lithium iron phosphate battery packs are much higher than those of lead-acid batteries, many people are willing to go to the market to buy new lithium batteries to replace old lead-acid batteries.
