Inside Back Cover: Direct Detection of Discharge Products in Lithium–Oxygen Batteries by Solid‐State NMR Spectroscopy (Angew. Chem. Int. Ed. 34/2012)

Characterizing the electrochemical products formed in the lithium‐oxygen battery is a necessary step in its development as a viable energy storage system. In their Communication on page 8560 ff., C. P. Grey et al. demonstrate that by using 17O‐enriched oxygen gas the electrochemical products formed on the surface of the carbon electrode in various electrolytes can be detected and identified by solid‐state NMR spectroscopy.
