diffusion coefficient

Galvanostatic Intermittent Titration Technique

The Galvanostatic Intermittent Titration Technique or GITT as most know it in the world of battery chemistry and modelling as it is used to estimate diffusion coefficients, OCV, over-potentials and resistance. First described by Weppner and R. A. Huggins [5]. The GITT measures the transient voltage change and open circuit voltage (OCV) change during the charging … Read more
