Cation order, with a local structure related to γ-LiFeO, is observed in the nominally cation-disordered Li-excess rocksalt LiNbMnOvia X-ray diffraction, neutron pair distribution function analysis, magnetic susceptibility and NMR spectroscopy. The correlation length of ordering depends on synthesis conditions and has implications for the electrochemistry of these phases.
通过X射线衍射、中子对分布函数分析、磁化率和核磁共振光谱,在名义上阳离子无序的富锂岩盐LiNbMnO中观察到与γ-LiFeO相关的局部结构的阳离子有序排列。有序排列的关联长度取决于合成条件,并对这些相的电化学有影响。
