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.
