Lithium iron phosphate battery safety:

1. Lithium iron phosphate is currently the safest cathode material for lithium-ion batteries, which does not contain any heavy metal elements harmful to the human body, and it is difficult for oxygen to precipitate in its olivine structure, which improves the stability of the material.

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

3. Charging and discharging are the two basic working states of lithium batteries. When the lithium iron phosphate battery is charged and discharged, due to the weak oxidation ability of iron ions, it will not release oxygen, and it is naturally difficult to have a redox reaction with the electrolyte, which makes the charging and discharging process of the lithium iron phosphate battery in a safe environment. Not only that, lithium iron phosphate batteries are difficult to undergo violent redox reactions in the process of large-rate discharge, or even overcharge and discharge. At the same time, after lithium is deintercalated, the final volume of the unit cell (the smallest constituent unit of the crystal) will be reduced due to the change of lattice, which just offsets the increase in the volume of the carbon anode in the reaction, so the lithium iron phosphate battery can maintain the stability of the physical structure during charging and discharging, eliminating the hidden danger of battery bursting due to the increase in volume.
