Corrigendum: Towards an Understanding of Li2 O2 Evolution in Li-O2 Batteries: An In Operando Synchrotron X-ray Diffraction Study.

Abstract

An error in the units of the y axis of Figure 2 d was found. The units should be Å instead of nm (1 nm=10 Å). In the published Full Paper, there were no conclusions related to these absolute values that would affect the scientific content of this publication. The original and corrected Figure 1 is shown below. Left: original, right: corrected. (a) Galvanostatic discharge–charge of Li–O2 cells with CNT electrode, (b) showing the evolution of Li2O2 mass, (c) the efficiency (%) of Li2O2, and (d) the average domain size as a function of time at current density of 0.15 mA cm−2, respectivly. The gray region corresponds to a temporary loss of beam. The text on page 4 (left column) of the Full paper should read: “Figure 2d shows that the average Li2O2 domain size sharply increased to 170 Å during the first discharge step with growth along both [100] and [101] directions. During the following part of discharge, the average domain size was reduced to 120 Å, with the size along the [101] direction remaining unchanged whereas that along the [100] direction decreased.” And the text on page 4 (right column) should read: “From FullProf refinements, we obtained the apparent dimensions of 170 and 80 Å for the (100) and (101) reflections at the end of discharge.” In addition, Figure S2 in the Supporting Information was also updated. Left: original, right: corrected. (Original) (a) Galvanostatic discharge–charge of Li–O2 cells with CNT electrode, (b) the evolution of the Li2O2 mass, (c) the efficiency (%) of Li2O2 evolution, and (d) the average domain size as a function of time at current density of 0.075 mA cm-2, respectively. The authors and the editorial office apologize for this oversight and for any inconvenience caused.
