Direct Observation of Ordered Oxygen Defects on the Atomic Scale in Li2O2 for Li-O2 Batteries

The structure of the discharge product, Li2O2, in lithium‐oxygen batteries is revealed directly on the atomic scale. A unique stage ordering that the peroxide vacancy occupies preferentially in every other layer along the c‐axis of Li2O2 is observed. This finding provides new insight into the relati...

Description
Summary:The structure of the discharge product, Li2O2, in lithium‐oxygen batteries is revealed directly on the atomic scale. A unique stage ordering that the peroxide vacancy occupies preferentially in every other layer along the c‐axis of Li2O2 is observed. This finding provides new insight into the relationship between the structure of Li2O2 and the discharge/charge behavior of Li‐O2 batteries.
