Controlling iron versus oxygen redox in the layered cathode Na0.67Fe0.5Mn0.5O2: mitigating voltage and capacity fade by Mg substitution
Layered oxides for Na-ion batteries containing Fe have attracted strong interest mainly due to their low cost. However, full oxidation of Fe3+ to Fe4+ is rarely seen before O-redox sets in and is typically accompanied by voltage and capacity fade on cycling. On charging P2-Na0.67[Fe0.5Mn0.5]O2, Fe3+...
