From the aforementioned discussion, it is clear that the redox behaviour of all materials is dominated by Ni along with Mn redox in the Sc-doped material to a minor degree (see Supporting Information for further details). As for the oxygen, all compositions show quite some fluctuation around 0 UPE (number of unpaired electrons) both at the OCV and fully charged state (Figure ). The most UPE on the oxygens show a minor drift towards values slightly higher than 0 for the OCV state.
