As a potential low-cost and high energy density energy storage technology, rechargeable Mg batteries (RMBs) have shown renaissance in the last decade, since the first realization of Mg electrochemical deposition nearly a century ago. Based on the Chervel phase Mo₆S₈ cathode, metal Mg anode, and organohaloaluminate electrolyte, the first RMB prototype was constructed, and more and more investigations are being committed to advance RMB system after that. In this review, we first overview the current status and challenges of Mg-ion techniques. Recent developments on critical components of RMBs, i.e., cathode and anode materials, are then analyzed systematically. Based on these understandings on the state-of-the-art RMBs, potential improving strategies are proposed to provide insights on future development of RMBs.

作为一种潜在的低成本和高能量密度储能技术，可充电镁电池（RMBs）自近百年前首次实现镁电化学沉积以来，在过去十年中呈现出复兴。基于 Chervel 相 Mo ₆ S ₈正极、金属镁负极和有机卤铝酸盐电解质，构建了第一个人民币原型，之后越来越多的研究致力于推进人民币系统。在这篇综述中，我们首先概述了镁离子技术的现状和挑战。人民币关键组成部分的最新进展，即然后系统地分析正极和负极材料。基于对最先进人民币的这些理解，提出了潜在的改进策略，以提供对人民币未来发展的见解。
