Corrigendum: Synergy of Weakly‐Solvated Electrolyte and Optimized Interphase Enables Graphite Anode Charge at Low Temperature

Abstract

It has come to the authors’ attention that an inadvertent error was made during the preparation of Figure 2 f and Figure 3 d in this Communication. In Figure 2 f the label for the Y axis should read Rt(Ω). In Figure 3 d the original line (grey line) and fitting line (red dotted line) for C1s at −20 °C SEI were copied by mistake during the plotting. The corrected versions of Figures 2 and 3 are shown below. The changes do not alter the interpretation of the data or the conclusions of the published work. The authors sincerely apologize for the mistakes. The electrochemical behaviors of Gr electrodes under different formation temperatures. a) The voltage evolution profiles of Li||Gr half cells under different working temperatures to indicate the capacities and initial coulombic efficiencies. b) Schematic diagram of Gr||Gr cell and its equivalent circuit used for the impedance analysis, with the only impedance of Li+ migrating through SEI (Rt). The impedance evolution profiles of Gr||Gr cells (with different SEI formation temperatures) under test temperature of c)+40 °C, d)+25 °C and e) −20 °C, respectively. f) The corresponding fitted Rt values under different test temperatures. The SEI film analysis of Gr electrodes under different formation temperatures. The TEM images of Gr electrode with SEI thickness under formation temperature of a)+40 °C, b)+25 °C and c) −20 °C, respectively. d–f) The fitted XPS analysis (C1s, F1s, O1s spectra) of Gr electrodes under different formation temperatures.
