The Ni oxidation state in Li_1−xNi_0.5Mn_1.5O₄ (LNMO) within a composite electrode mapped by soft X-ray scanning transmission X-ray microscopy (STXM) has shown unexpected distinct variations in phase separation among and within individual battery particles, which has been experimentally correlated to both their morphology and interface structure for the first time. The obtained new insights will assist the further development of long-life high voltage LNMO batteries.

多孔复合电极内 Li _{1- x} Ni _0.5 Mn _1.5 O ₄中的意外相分离†

通过软X射线扫描透射X射线显微镜（STXM）测绘的复合电极中Li _{1- x} Ni _0.5 Mn _1.5 O ₄（LNMO）中的Ni氧化态显示出单个电池之间和内部的相分离出乎意料的明显变化颗粒，这在实验上首次与它们的形态和界面结构相关。获得的新见解将有助于长寿命高电压LNMO电池的进一步开发。
