Galvanostatic Intermittent Titration Technique (GITT)


This Application Note shows how AUTOLAB and NOVA is used to perform GITT tests on a Li-ion battery. Here,
galvanostatic charge pulses are applied, each followed by relaxation time, until the upper potential limit is reached. Then, discharge pulses are applied, followed by equilibration time, until the lower potential limit is reached. From the potential vs. time plot, important information for calculating the diffusion coefficient and thermodynamics parameters quantities can be obtained.
