Correction to: Zwitterionic Sulfobetaine Hydrogel Electrolyte Building Separated Positive/Negative Ion Migration Channels for Aqueous Zn-MnO 2 Batteries with Superior Rate Capabilities (Advanced Energy Materials, (2020), 10, 16, (2000035), 10.1002/aenm.202000035)

Abstract

Adv. Energy Mater. 2020, 10, 2000035 DOI: 10.1002/aenm.202000035 In the originally published manuscript an incorrect ¹H-NMR spectra of the [2-(Methacryloyloxy)ethyl]diethy-(3-sulopropyl) (MAEDS) monomer in Figure 1b and its magnified figure (Figure S1a) was presented. Two independent testing agencies have retested the ¹H-NMR of MAEDS, and the correct spectra including the carefully modified signal assignments is shown in the corrected Figure 1 and Figure S1a on pages 2 and 3 respectively. 1 Figure (Figure presented.) Schematic of the fabrication of the ZSC-gel matrix. (a) Semi-interpenetrating networks of the ZSC-gel consisting of zwitterionic sulfobetaine and cellulose nanofibril chains. (b) Synthesis of the ZSC-gel. The square frame indicates the migration channel for Zn²⁺ and SO<inf>4</inf>²⁻ ions. S1 Figure (Figure presented.) (a) 1H-NMR spectra and molecular formula of the MAEDS monomer. The characteristic resonance peaks appear at δ = 1.84, 2.18, 2.87, 3.12, 3.50, 3.73, 4.54, 5.68 and 6.07 ppm are well consistent with the protons of the MAEDS-segments according to the literature (“Schönemann et al., Polymers 2018, 10, [639], https://doi.org/10.3390/polym10060639” and “Polymer, 1994, 35(10): 2210–2217”). (b) Molecular formula and of nanofibrillated cellulose. The references to extraction of the chemicals from celery and Beta vulgaris L. have also been removed from the new Figure 1. The monomer of cellulose nanofibrils was bought from “Tianjin Woodelf Biotechnology Co., Ltd.” The MAEDS was bought from Aladdin. In addition the specific sulfobetaine used in the work has not been found in natural plants. Therefore, the claim that “all monomers are natural” was incorrect. These errors do not affect the accuracy of the work's scientific conclusions. The authors apologize for these errors and any inconvenience caused.
