Abstract
Correction for ‘An aqueous hybrid electrolyte for low-temperature zinc-based energy storage devices’ by Nana Chang et al., Energy Environ. Sci., 2020, 13, 3527–3535, https://doi.org/10.1039/D0EE01538E.
In Fig. 2c on page 3530 of this article, the previous notation of “10−5” should be corrected to “10−8” in the y-axis label on the right, due to a mistake in the process of converting “Å2 nS−1” (unit of theoretical calculation) into “cm2 S−1” (unit of picture presentation). There is no description of the value of the diffusion coefficient, only the discussion about the trend.
Fig. 2c should appear as follows:
 | ||
| Fig. 2 (c) Coordination numbers of H2O, EG, and SO42− around Zn2+ and the diffusion coefficient of Zn2+ in different electrolytes calculated from MD simulations. | ||
The discussion of the diffusion coefficient in Fig. 2c should be as follows:
“Moreover, the diffusion rate of Zn2+ in these electrolytes can be qualitatively evaluated by the mean-squared displacement (MSD) as a function of time (Fig. S13, ESI†). Surprisingly, the diffusion coefficient of Zn2+ rises and then declines as the EG content increases (Fig. 2c). When the EG-to-water ratio is lower than 60%, the diffusion coefficient of the hybrid electrolyte is still higher than that of EG0. This result shows that the solvation structure of Zn2+ coordinated with EG and H2O contributes to the fast transport of Zn2+. Nevertheless, the calculated fast ion diffusion coefficient of Zn2+ is not quite consistent with the slight decrease in the ionic conductivities of the hybrid electrolytes at 20 °C (Fig. 1b), which probably results from the gradually increasing viscosities of the hybrid electrolytes (Fig. S3, ESI†). Even so, fast Zn-ion transport in the hybrid electrolyte is achieved at low temperatures, when the solvation interaction of EG with Zn2+ becomes more prominent.”
This correction does not have any impact on the core idea and conclusion of this work.
