Atomic layer deposition of Al 2 O 3 is employed as ultrathin coating on LiNi 0.5 Mn 1.5 O 4 , a high voltage cathode in Li‐ion batteries. X‐ray absorption spectroscopy and scanning transmission electron microscopy electron energy loss spectroscopy show that the coating suppresses Mn 2+ formation on the surface and decelerates impedance buildup. The detailed analysis by Chongwu Zhou and co‐workers is shown in article number 1602873.
