When the LFP battery is discharged, lithium ions are deintercalated from the graphite crystal, enter the electrolyte, and pass through the separator. Then, it migrates to the surface of the lithium iron phosphate crystal through the electrolyte, and then is embedded into the crystal lattice of the lithium iron phosphate again through the surface.
The lithium was selectively leached to achieve the separation of lithium and iron. The use of salt as a leaching agent can be recycled in the recycling process. More and more lithium iron phosphate (LiFePO 4, LFP) batteries are discarded, and it is of great significance to develop a green and efficient recycling method for spent LiFePO 4 cathode.
When the LFP battery is charged, lithium ions migrate from the surface of the lithium iron phosphate crystal to the surface of the crystal. Under the action of the electric field force, it enters the electrolyte, passes through the separator, and then migrates to the surface of the graphite crystal through the electrolyte.
Therefore, the lithium element in lithium iron phosphate can be leached out in just ten minutes. As the hydrothermal reaction continues, pH of the solution rises due to the consumption of H + in the solution, which results in the partial lithium returning to the solid.
The positive electrode material of lithium iron phosphate batteries is generally called lithium iron phosphate, and the negative electrode material is usually carbon. On the left is LiFePO4 with an olivine structure as the battery’s positive electrode, which is connected to the battery’s positive electrode by aluminum foil.
Lithium iron phosphate batteries can last up to 10 years. However, despite their long lifespan, the power of this battery will begin to decline. When your LFP batteries can’t do their job anymore, contact Battery Recyclers of America to ensure safe handling and recycling of the materials in the battery.
Lithium iron phosphate batteries also provide excellent chemical stability, which considerably improves the safety of using the battery. Even in situations where they are overheated or short-circuited, the oxygen atoms are extremely hard to remove.
