2.1. Cell selection The lithium iron phosphate battery, also known as the LFP battery, is one of the chemistries of lithium-ion battery that employs a graphitic carbon electrode with a metallic backing as the anode and lithium iron phosphate (LiFePO 4) as the cathode material.
When discharging, the reverse process happens, and lithium ions are intercalated into the material from the electrolyte. The intercalation sequence of lithium ions proceeds from the outside to the inside along the radial spherical reaction interface.
However, due to the influence of the lithium ions diffusion rate (the same reason as for the residual spherical nuclei in the Radial Model), there will still be a small spherical FP core remaining after the discharge process is completed, which is also a cause of capacity loss .
For the first time, the self-discharge of rechargeable batteries induced by parasitic reactions is elucidated from the sight of the Evans Diagram, which is an effective method used in corrosion science for analyzing the coupled relationship between kinetics and thermodynamics.
Consequently, it has become a highly competitive, essential, and promising material, driving the advancement of human civilization and scientific technology. The lifecycle and primary research areas of lithium iron phosphate encompass various stages, including synthesis, modification, application, retirement, and recycling.

Official Depth Of Discharge Recommendations For LiFePO4
Battleborn says this: "Most lead acid batteries experience significantly reduced cycle life if they are discharged more than 50%, which can result in less than 300 total cycles. Conversely LIFEPO4 (lithium iron phosphate) batteries can be continually discharged to 100% DOD and there is no long term effect.
