摘要：
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. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
