Berichtigung: Ether‐Based Electrolyte Chemistry Towards High‐Voltage and Long‐Life Na‐Ion Full Batteries

Abstract

In this Research Article, the calculated concentration values for all five electrolytes (i.e., ND-1, ND-2, NDD-3, 2.83 m NaPF6 in DEGDME, and 3.2m-NaPF6 in DEGDME/DOL) are inaccurate. Owing to the miscalculation for molality, the corresponding descriptions of electrolyte concentration in the main text and Supporting Information are inconsistent with the electrolytes that were actually used. After careful recalculation, the relevant text should be modified as follows: In the Introduction section, “3.04 m NaPF6 in diethylene glycol dimethyl ether (DEGDME) with the addition of 1,3-dioxolane (DOL) diluent (10:1 by volume ratio)” should be revised to “3.36 m NaPF6 in diethylene glycol dimethyl ether (DEGDME) with the addition of 1,3-dioxolane (DOL) diluent (10:1 by volume ratio)” based on the following equation and calculation: Where the density and molecular weight (M) of DEGDME is 0.94 g/mL and 134.17. The density and M of DOL is 1.06 g/mL and 74.08. The molar (m) ratio of NaPF6/DEGDME/DOL is equivalent to 5:10:2 for actual NDD-3 electrolyte. Similarly, “0.94 m NaPF6 in DEGDME” (i.e., ND-1), “1.88 m NaPF6 in DEGDME” (i.e., ND-2), “2.83 m NaPF6 in DEGDME”, and “3.2m-NaPF6 in DEGDME/DOL” should be “1.06 m NaPF6 in DEGDME”, “2.13 m NaPF6 in DEGDME”, “3.19 m NaPF6 in DEGDME”, and “3.83m-NaPF6 in DEGDME/DOL”, respectively, in the main text and/or Supporting Information. These changes are due to a miscalculation, rather than the experimental processes, and do not affect the interpretation of the data, discussion, or conclusions. The main contents and conclusions of the original Research Article are not affected by this Corrigendum. The authors apologize for this oversight, and thank Mr. Xiangjun Pu and Prof. Yuliang Cao from Wuhan University for making us aware of this issue.
