Voltage Hysteresis in a Lithium Iron Phosphate (LFP) Electrode

Application ID: 142011


Lithium iron phosphate (LFP) is a common positive electrode material in lithium-ion batteries. Specific for the LFP electrode material is that its equilibrium (open circuit) potential, when defined as a function of the lithiation state, features a large flat plateau with a more or less constant potential. The plateau also exhibits voltage hysteresis, that is: a difference in the plateau potential between lithiation and delithiation cycling, also referred to as a zero-current voltage gap.

This tutorial demonstrates a simplified model to include voltage hysteresis in a porous LFP electrode.

This model example illustrates applications of this type that would nominally be built using the following products:
