The Front Cover illustrates 2 kinds of synthesized Mn‐doped Na3Ni2−xMnxSbO6 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.More information can be found in the Article by S. Okada and co‐workers.

锰掺杂对钠离子电池Na3Ni2SbO6的结构和电化学性能的影响
前盖说明了用于Na离子电池的2种合成的Mn掺杂的Na 3 Ni 2− x Mn x SbO 6层状氧化物正极活性材料。由于较小的晶胞体积变化，左侧的轻掺杂Mn（x = 0.25）样品增强了O'3-P'3相变动力学。另一方面，右侧的重掺杂（x = 0.5）样品存在较大的极化，这对应于减小的两相反应范围和钠萃取后的大晶胞体积变化。冈田S.及其同事的文章中。
