Potentiostatic intermittent titration technique (PITT)
Summary
During charge and discharge of a Li-ion battery, lithium ions are transported from one electrode through the electrolyte to the other electrode. Knowing the chemical diffusion coefficient of electrode materials is crucial. The potentiostatic intermittent titration technique (PITT) is one of the most used techniques to retrieve insights on the diffusion coefficient of the electrode active materials.
