Currently, species charge is interpreted as a full point charge, while ions are point charges of full oxidation state value. Two developments are necessary.
- Allow ions to be represented by their partial oxidation states as obtained from Bader population analysis of undoped lattice structure.
- Allow species to be represented as polarons with a finite size, within which the charge is dispersed. Charge dispersion information is also need to be sourced from Bader population analysis of charge localized lattice structure.
