摘要
Current electrochemical energy storage technology has evolved a variety of rechargeable battery systems.Recently,the resource shortage of raw materials in commercially available lithium-ion batteries has attracted widespread attention.The requirements to meet resourcefulness,sustainability,safety,and high energy density have motivated the development of rechargeable magnesium-ion batteries(RMBs).Although RMBs have made significant progress so far,there are still many obstacles to practical orientation.We systematically summarize the significant progress and the latest research on RMBs,including Mg^(2+)-conducting electrolytes,Mg^(2+)-storage cathodes,and Mg-based anodes.In this review,we mainly introduce the properties and features of various Mg^(2+)-conductive electrolytes,the mainstream cathode materials,and their respective Mg^(2+)-storage mechanisms,as well as the Mg metal(or alloy)anodes and the corresponding modification strategies.Finally,the future directions in various key components for RMBs are highlighted.
