Abstract
Rechargeable metal-bromine batteries have emerged as promising candidates to develop competitive, cost-effective, high-energy-density energy storage systems. The general configuration of a metal-bromine battery includes a metal anode and a bromine cathode. The emergence of zinc-bromine redox batteries (ZBRBs) is attributed to the earth's abundance of zinc, the cost-effectiveness of the active materials, and the high theoretical energy density. Recent advancements have highlighted using bromides (Br−, Br2, and Brn− (n = 3, 5, 7 …)) entrapping materials for the cathode to enhance the Br−/Br2 redox reaction and inhibit the Br2 diffusion in the ZBRBs. This review aims to explore the various arrangements and insights into bromides-entrapping-based cathodes recently reported. Finally, we share perspectives on the remaining challenges and prospects for the ZBRBs.
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 •
