Abstract

Atomic layer deposition of Al2O3 is employed as ultrathin coating on LiNi0.5Mn1.5O4, 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 Mn2+ formation on the surface and decelerates impedance buildup. The detailed analysis by Chongwu Zhou and co-workers is shown in article number 1602873.
