What is the production process of lithium iron phosphate battery?

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 single cell 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?

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

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 managed strictly and meticulously, so as to improve Lithium battery 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 cell production, and the third is battery assembly. In the assembly and production process of lithium iron phosphate batteries, the production of pole pieces is the foundation, and the production of batteries is the core. Battery assembly is related to the quality of finished lithium batteries.

Lithium batteries have high requirements on the environment, and a slight discomfort in the environment will cause explosion and fire, so they cannot be used at will like lead-acid batteries. Therefore, non-professionals suggest not to assemble lithium batteries privately.
