September 2014Transmission electron microscope (TEM) image of a cycled LiNi0.5Mn1.5O4 thin film electrode, showing the cathode electrolyte interphase (CEI) on its surface. This interface film is composed of organic as well as inorganic decomposition products of the electrolyte, the electrolyte salt as well as of reaction products between the electrolyte and the cathode. It shows a stacked microstructure. Rather inorganic species are located close to the electrode, whereas more organic ones are situated near the electrolyte.The thin film electrode was deposited by pulsed laser deposition onto a platinum covered YSZ single crystal. The TEM images were recorded at the Institute of Materials Physics, University of Münster. Thanks to Y. Hamedi and Dr. F. Berkemeier for these measurements.
