Transference number is defined as the number of Faradays of charge carried by the cations across a reference plane when a total of one faraday of charge passes across the plane.

The potentiostatic intermittent titration technique (PITT)^[1] is, together with its galvanostatic counterpart, one of the most used techniques to retrieve insights on the diffusion coefficient of the electrodes’ active materials.

The GITT procedure consists of a series of current pulses, each followed by a relaxation time, in which no current passes through the cell. The current is positive during charge and negative during discharge.

The charge–discharge cycling performance was investigated using a multichannel potentio-, galvanostat (TOSCAT-3100, TOYO system) in a temperature-controlled chamber.

Coulombic efficiency, CE, is the ratio of discharge capacity over charge capacity of a specific electrode in a cell, as shown in the following equation^[1].
