Technical Data: Constant Voltage Intermittent Titration Method (PITT)
The potentiostat intermittent titration technique (PITT) is one of the most commonly used methods to gain insights into the diffusion coefficients of electrode active materials.
During the charging and discharging of lithium-ion batteries (Li-ion batteries), lithium ions are transported from one electrode through the electrolyte to the other electrode. Knowing the chemical diffusion coefficient of the electrode materials is very important. The potentiostat intermittent titration technique (PITT) is one of the most commonly used methods to gain insights into the diffusion coefficients of electrode active materials.
basic information
Li-ion batteries are one of the most researched energy storage devices due to their relatively high energy and power performance. During the charging and discharging of Li-ion batteries, Li ions are transported from one electrode to the other through the electrolyte. Here, diffusion of Li ions into the bulk material occurs. In this regard, the diffusion coefficient of the active material present in the electrode directly affects battery performance. Therefore, knowing the chemical diffusion coefficient of the electrode material is extremely important. The potentiostatic intermittent titration technique (PITT) is commonly used in conjunction with its galvanostatic counterpart, GITT, to gain insights into the diffusion coefficient of the active material in the electrode.
