The lithium iron phosphate battery (LiFePO 4 battery) or lithium ferrophosphate battery (LFP battery), is a type of Li-ion battery using LiFePO 4 as the cathode material and a graphitic carbon electrode with a metallic backing as the anode 53, 54, 55.
The electron flow in a discharging lithium-ion battery is driven by the chemical reaction.
The enthalpy change in the reaction is similar, ΔrH° = −337 kJ mol−1.28 The entropic contribution to the free-energy change, −298 K ΔrS° = +6 kJ mol−1, is less than 2% of ΔrG° and therefore quite insignificant.6 The strongly negative values confirm that discharge in a lithium iron phosphate battery is energetically strongly downhill.
Standard charge and discharge processes of Li-ion battery. Step I (CC discharge): The battery is discharged at constant current \ ( {I}_ {c1}\) until the voltage drops to the cutoff voltage \ ( {V}_ {cut}\).
In these types of devices, lithium-ion batteries are commonly used nowadays, and in particular their variety—lithium iron phosphate battery—LiFePO4. Apart from the many advantages of this type of battery offers, such as high power and energy density, a high number of charge and discharge cycles, and low self-discharge.
It may be important here to conceptually distinguish between an open lithium-ion cell on the one hand and a discharging, possibly reversible, cell on the other. In an open cell, electrons do show up in the overall reaction, see eqn (S69) (ESI †), but since they do not travel through an external circuit, no electrical energy is released.
