Abstract

Aqueous zinc-ion Batteries (ZIBs) using metallic Zn anode exhibit significant potential for grid-scale stationary energy storage. However, Zn dendrite growth, associated with various side reactions, constrains the reversibility of Zn deposition/dissolution, severely hindering the practical deployment of ZIBs. Electrolyte, also known as the “blood” of the batteries, has been a hot research topic because its specific formulation is decisive to the reversibility of Zn anode. In view of the rapid progresses in this area, in this review, we provide a concise overview of recent advances in electrolyte engineering for Zn stabilization. In contrast to previous reviews focusing on electrolyte composition or effects, we summarize and discuss the impact of electrolyte on the four key stages of Zn deposition from an electrochemical perspective. It is anticipated to give some enlightening clues to the deep understanding of the underlying mechanisms of electrolyte-mediated Zn chemistry.

锌离子水电池中无树枝状晶锌沉积的电解质配方研究进展
使用金属锌阳极的锌离子水电池(ZIB)在电网规模的固定储能方面具有巨大潜力。然而,与各种副反应相关的锌枝晶生长限制了锌沉积/溶解的可逆性,严重阻碍了锌离子电池的实际应用。电解液也被称为电池的 "血液",一直是热门研究课题,因为其具体配方对锌阳极的可逆性起着决定性作用。鉴于这一领域的快速发展,我们在本综述中简要概述了用于稳定锌的电解质工程的最新进展。与以往侧重于电解质成分或影响的综述不同,我们从电化学角度总结并讨论了电解质对锌沉积四个关键阶段的影响。预计这将为深入理解电解质介导的锌化学的内在机制提供一些启发性线索。

期刊介绍: The development of the Current Opinion journals stemmed from the acknowledgment of the growing challenge for specialists to stay abreast of the expanding volume of information within their field. In Current Opinion in Electrochemistry, they help the reader by providing in a systematic manner: 1.The views of experts on current advances in electrochemistry in a clear and readable form. 2.Evaluations of the most interesting papers, annotated by experts, from the great wealth of original publications. In the realm of electrochemistry, the subject is divided into 12 themed sections, with each section undergoing an annual review cycle: • Bioelectrochemistry • Electrocatalysis • Electrochemical Materials and Engineering • Energy Storage: Batteries and Supercapacitors • Energy Transformation • Environmental Electrochemistry • Fundamental & Theoretical Electrochemistry • Innovative Methods in Electrochemistry • Organic & Molecular Electrochemistry • Physical & Nano-Electrochemistry • Sensors & Bio-sensors •
