In the original article, we calculated reaction enthalpies (?Hr) using the thermochemical data in the Materials Project database, obtained from density functional theory, and in the Reaction Calculator. Due to the recent update of the database, i.e., recalculation of Li5CoO4, the ?Hr of eq 9 has been changed from +13 to -14 kJ mol-1. This change rather supports general experimental data, as mentioned in the original article (page 43609, left column, lines 6-8). According to the updated data, we have corrected parts of discussions in the reaction mechanisms as follows: (i) Li5CoO4 ? LiCoO2 + 2Li2O (?Hr = -14 kJ mol-1) (9’) (page 43608, right column, lines 31-32). (ii) The oxidation reaction eq 4 proceeds by a deintercalation reaction, probably due to its lower activation energy compared with the transition from tetrahedrally coordinated Co oxides to their octahedrally coordinated counterparts (page 43608, right column, lines 27-30). (iii) The reduction reaction eq 7 is consistent with eq 9’ (page 43609, left column, lines 1-8). We state that the changes have no effect on the whole reaction mechanisms and conclusions.
