## Description

- description: High-entropy layered oxide materials containing various metals that
    exhibit smooth voltage curves and excellent electrochemical performances have
    attracted attention in the development of positive electrode materials for sodium-ion
    batteries. However, the smooth voltage curve can be obtained by suppression of
    the Na+-vacancy ordering, and therefore, it is not necessary to use a greater
    variety of metals than necessary. In this study, the Na+-vacancy ordering is found
    to be disturbed by dual substitution of TiIV for MnIV and ZnII for NiII in P2-Na2/3[Ni1/3Mn2/3]O2.
    Dual-substituted Na2/3[Ni1/4Mn1/2Ti1/6Zn1/12]O2 demonstrates almost non-step voltage
    curves with a reversible capacity of 114 mAh g-1 and less structural changes with
    maintaining a high crystalline structure during charging and discharging. Synchrotron
    X-ray, neutron, and electron diffraction measurements reveal that dual-substitution
    with TiIV and ZnII uniquely promotes in-plane NiII-MnIV ordering, which is quite
    different from the disordered mixing in conventional multiple metal substitution.
