Incremental Capacity Analysis ICA

The redox potential of insertion electrodes is normally represented by the derived form of Eq. (3.12), which, when K = 0, can be written under the form  

Equatimi (13.30) predicts an S-shaped potential curve as a function of moles of species involved in the insertion process. In such a case, (dxIdV) defines the capability of storing or delivering charge at a potential V. In practice, however, the interaction T-term is not negligible, so that the full Eq. (13.2) must be written at each incremental step i, letting K depend on i, since the interaction may depend oti the lithium concentration. To make contact with [20, 21], we use their notations, and write the electrode potential for x,- i x,- x,+1 under the form
