Design of a Solid Electrolyte Interphase for Aqueous Zn Batteries

Li, Dan, Cao, Longsheng, Deng, Tao, Liu, Sufu, Wang, Chunsheng·2021·Angewandte Chemie International Edition

Abstract

Aqueous Zn batteries are challenged by water decomposition and dendrite growth due to the absence of a dense Zn‐ion conductive solid electrolyte interphase (SEI) to inhibit the hydrogen evolution reaction (HER). Here, we design a low‐concentration aqueous Zn(OTF)2‐Zn(NO 3)2 electrolyte to in situ form a robust inorganic ZnF 2‐Zn 5(CO 3)2(OH)6‐organic bilayer SEI, where the inorganic inner layer promotes Zn‐ion diffusion while the organic outer layer suppresses water penetration. We found that the insulating Zn 5(OH)8(NO 3)2⋅2 H 2 O layer is first formed on the Zn anode surface by the self‐terminated chemical reaction of NO 3− with Zn 2+ and OH− generated via HER, and then it transforms into Zn‐ion conducting Zn 5(CO 3)2(OH)6, which in turn promotes the formation of ZnF 2 as the inner layer. The organic‐dominated outer layer is formed by the reduction of OTF−. The in situ formed SEI enables a high Coulombic efficiency (CE) of 99.8 % for 200 h in Ti∥Zn cells, and a high energy density (168 Wh kg−1) with 96.5 % retention for 700 cycles in Zn∥MnO 2 cells with a low Zn/MnO 2 capacity ratio of 2:1.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
