The Front Cover illustrates 2 kinds of synthesized Mn‐doped Na 3 Ni 2− x Mn x SbO 6 layered oxide cathode active materials for Na‐ion battery. The light Mn doped (x=0.25) sample in the left side is enhanced the O’3‐P’3 phase transition kinetics due to the smaller unit‐cell‐volume changes. On the other hand, the heavily doped (x=0.5) sample in the right side suffers from large polarization, corresponding to the reduced two‐phase reaction range and a large unit‐cell‐volume change upon sodium extraction.
