      abstract     = {Oxygen-redox-based cathode materials for sodium-ion
                      batteries (SIBs) have attracted considerable attention in
                      recent years owing to the possibility of delivering
                      additional capacity in the high-voltage region. However,
                      they still suffer from not only fast capacity fading but
                      also poor rate capability. Herein,
                      P2-Na0.75[Li0.15Ni0.15Mn0.7]O2 is introduced, an
                      oxygen-redox-based layered oxide cathode material for SIBs.
                      The effect of Ni doping on the electrochemical performance
                      is investigated by comparison with Ni-free
                      P2-Na0.67[Li0.22Mn0.78]O2. The Na0.75[Li0.15Ni0.15Mn0.7]O2
                      delivers a specific capacity of ≈160 mAh g−1 in the
                      voltage region of 1.5–4.6 V at 0.1 C in Na cells. Combined
                      experiments (galvanostatic cycling, neutron powder
                      diffraction, X-ray absorption spectroscopy, X-ray
                      photoelectron spectroscopy, and nuclear magnetic resonance
                      (7Li NMR)) and theoretical studies (density functional
                      theory calculations) confirm that Ni substitution not only
                      increases the operating voltage and decreases voltage
                      hysteresis but also improves the cycling stability by
                      reducing Li migration from transition metal to Na layers.
                      This research demonstrates the effect of Li and Ni co-doping
                      in P2-type layered materials and suggests a new strategy of
                      using Mn-rich cathode materials via oxygen redox with
                      optimization of doping elements for SIBs.},
