The authors noticed that the values of exchange current density in Figures 1 c, 3 b, S6 and S16 were calculated incorrectly due to the reverse of x and y axes during the linear fitting. The corrected values were calculated by the equation log i = (hÀa)/b, and presented in the revised Figures S6 and S16 (see the Supporting Information published online along with this Corrigendum). Revised versions for Figures 1 c and 3 b are shown below. Instead of having a negative correlation with the FEC

Thus, the formation of a lithium fluoride richer SEI actually enhances the charge transfer process. Still, the exchange current density stabilized at the reported critical FEC ratios for both FEC/EMC and FEC/EA systems. The results still clearly indicate the existence of critical FEC ratios for both FEC/EMC and FEC/EA systems and the critical FEC ratios are still highly consistent with the findings of the solvation, Coulombic efficiency, Li/Li cells and galvanostatic cycling studies. Therefore, this correction does not affect the conclusion of this paper, which stated that there existed a critical FEC ratio, at which the solvation number of FEC ! 1, for the FEC-based electrolyte systems. The authors apologize for this inadvertent error. Figure 1.
