1. The production process of lithium iron phosphate batteries is basically the same as that of other kinds of lithium batteries. The core processes of lithium phosphate batteries are batching, coating, roll pressing, sheeting and winding. In the batching process, the conductivity of lithium iron phosphate material is relatively poor, so the particles are generally made smaller. The objective effect of this is that the internal arrangement is more uniform, which promotes the formation of a balanced voltage platform, which can keep the battery stable when working.

2. Lithium iron phosphate is the safest cathode material for lithium-ion batteries at present. It does not contain any harmful heavy metal elements. Oxygen in olivine structure is difficult to precipitate, which improves the stability of the material.

3. Charging and discharging are two basic working states of lithium batteries. When lithium iron phosphate batteries are charged and discharged, it is difficult to react with electrolyte due to the weak oxidation ability of iron ions, which makes the charging and discharging process of lithium iron phosphate batteries in a safe environment. Moreover, it is difficult for lithium iron phosphate batteries to undergo severe redox reactions during high rate discharge, even during overcharge and discharge. At the same time, the final volume of the cell (the smallest component unit of the crystal) will be reduced due to the lattice change after lithium deintercalation, which offsets the volume increase of the carbon negative electrode in the reaction. Therefore, the lithium iron phosphate battery can maintain the stability of the physical structure during charging and discharging, eliminating the potential danger of battery burst caused by the volume increase.
