Abstract

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.
