I have explained more: The lithium iron phosphate battery (LiFePO 4 battery) or LFP battery (lithium ferrophosphate), is a form of lithium-ion battery which employs LiFePO 4 as the cathode material (inside batteries this cathode constitutes the positive electrode), and a graphite carbon electrode having a metal support forming the anode.
The lithium iron phosphate cells show stability in overcharge or short circuit conditions and they can withstand high temperatures . The cells are characterized by a uniform distribution of temperature with a little gradient between the internal and the surface regions .
However, the SOC has a higher influence on the internal resistance under low temperatures, because SOC affects the resistance value of the battery by influencing the disassembly and embedding speed of lithium ions in anode and cathode as well as the viscosity of electrolyte (Ahmed et al., 2015).
Lithium Polymer efficiencies are greater than 96% and higher than energy efficiencies of the two chemistries based Lithium Iron Phosphate. Internal resistance of Lithium Polymer cell is on average lower and almost constant during discharges. LiFePO 4 internal resistance is strongly variable.
