      abstract     = {Iron–manganese-based layered Na-ion cathodes are
                      appealing for building low-cost Na-ion batteries. However,
                      their practical realization is hindered by the lower
                      intercalation voltage (<3 V Na+/Na0) and limited cycle life.
                      To tackle these issues, we utilize Li/Cu-cosubstitution into
                      the O3–Na0.80(Fe0.50Mn0.50)O2 cathode to tune the
                      ionocovalency of Fe/Mn–O bonds, which in turn can modulate
                      the electrochemical properties. With the cosubstitution, the
                      intercalation voltage of Na0.80(Li0.10Cu0.10Fe0.30Mn0.50)O2
                      is raised to >3.2 V, thanks to the introduction of Cu3+/Cu2+
                      redox and enhanced Fe–O bond ionicity.
                      Na0.80(Li0.10Cu0.10Fe0.30Mn0.50)O2 displays extraordinary
                      cycling stability (98 and $60\%$ at 1C after 500 cycles in
                      the window of 4.0–2.0 and 4.0–1.5 V, respectively)
                      compared to the unsubstituted cathode (58 and $24\%$ at 1C
                      after 500 cycles in the window of 4.0–2.0 and 4.0–1.5 V,
                      respectively). The enhanced stability is attributed to the
                      retention of the O3-type structure and suppressed
                      Jahn–Teller MnO6 distortion during deep sodiation, as
                      revealed by X-ray diffraction and X-ray absorption
                      spectroscopy measurements and DFT calculations. This study
                      highlights the importance of chemical substitution
                      strategies in the development of advanced layered oxide
                      cathodes with higher energy densities and cycling
