Lithium iron phosphate battery is a lithium ion battery that uses lithium iron phosphate as the positive electrode material and carbon as the negative electrode material. The rated voltage of the monomer is 3.2V, and the charging cut-off voltage is 3.6V~ 3.65V. So what is the production process of lithium iron phosphate battery?

Production process of lithium iron phosphate battery

The production process of lithium iron phosphate battery is as follows: material preparation - homogenization - coating - rolling - slitting - baking - winding - into the shell - laser welding - baking - liquid injection - precharging - sealing - cleaning - aging - full inspection - warehousing - shipment. The production process of lithium iron phosphate battery is not very consistent for each manufacturer. As we all know, the production process of lithium battery is quite complicated. After all, the safety performance of lithium ion battery products is directly related to the life and health of consumers. There are high requirements for the performance, precision, stability and automation level of equipment in the production and manufacture of natural lithium batteries.

It can be seen that all production links in the production process of lithium iron phosphate battery packs are closely related to product quality and safety. Every link in the production process of lithium iron phosphate batteries must be strictly and carefully managed, so as to improve lithium batteries. Product safety performance.

What are the process steps of lithium iron phosphate battery assembly technology?

The production process of lithium iron phosphate battery is divided into three major sections, one is pole piece production, the other is battery cell production, and the third is battery assembly. In the assembly and production process of lithium iron phosphate battery, pole piece production is the foundation, battery cell production is the core, and battery assembly is related to the quality of finished lithium battery products.

Lithium batteries have high environmental requirements. A little environmental discomfort will cause explosion and fire, and cannot be used at will like lead-acid batteries. Therefore, non-professionals recommend not to assemble lithium batteries without permission.
