“…Figure S8 presents the EPR spectra of Na‐rich cathode materials Li 0.2 Na 1.0 Mn 0.8 O 2 . The EPR resonance of Li 0.2 Na 1.0 Mn 0.8 O 2 results from Mn 3+ and Mn 4+ is a broad spectrum of Lorentz‐governed result, showing a width of 1030.93 G between two symmetric peaks, consistent with previous reports and literatures . Normally, there is only one broad peak for Li 0.2 Na 1.0 Mn 0.8 O 2 .…”

“…This is in accordance with the previous studies of Stoyanova et al [32] and Nayaka et al [21]. It is an indicative of the ordered nature of the sample having paramagnetic interaction among 16d site ions in the spinel structure [33,34].…”

“…This result leads to the hypothesis of Fe 3+ clustering, which effectively contributes to the former broad line 12 . As the linewidth of the g ef ~ 4.3 resonance remains roughly constant, in practice the peak-to-peak amplitude of its derivative is proportional to the Fe concentration of the sample 13 15 , when neighboring spins become highly coupled 14 .…”
