Recent Progress on Layered Cathode Materials for Nonaqueous Rechargeable Magnesium Batteries

Abstract

Rechargeable magnesium batteries (RMBs) are promising candidates for next-generation energy storage systems owing to their high safety and the low cost of magnesium resources. One of the main challenges for RMBs is to develop suitable high-performance cathode materials. Layered materials are one of the most promising cathode materials for RMBs due to their relatively high specific capacity and facile synthesis process. This review focuses on recent progress on layered cathode materials for RMBs, including layered oxides, sulfides, selenides, and other layered materials. In addition, the effective strategies to improve the electrochemical performance of layered cathode materials are summarized. Moreover, future perspectives about the application of layered materials in RMBs are also discussed. This

Electrochemical Mg2+ Displacement Driven Reversible Copper Extrusion/Intrusion Reactions for High‐Rate Rechargeable Magnesium Batteries

“…[ 11,12 ] The reported cathode materials applied to RMBs are mainly based on intercalation or conversion mechanisms, including elemental sulfur, transition metal oxides, sulfides, selenides, etc. [ 13–18 ] However, the rate capability and cycling stability of the cathode materials are still to be further improved.…”

Density Functional Theory Calculations for the Evaluation of FePS3 as a Promising Anode for Mg Ion Batteries

“…As one of the most successful technology for energy storage, rechargeable lithium-ion batteries (LIBs) have been widely applied to scalable energy storage systems, electric vehicles, and portable electronic devices [3][4][5]. Although LIBs have become advanced and widely available rechargeable batteries, they have not been regarded as ideal sustainable sources of energy storage equipment because of the scarcity, high cost, and safety problems of lithium [6,7]. Magnesium-ion batteries (MIBs) have attracted increasing attention because of their low cost, safety, and natural abundance.…”

Covalent Organic Frameworks for Next‐Generation Batteries

“…Therefore, rechargeable magnesium ion batteries (MIBs) are very promising for large-scale energy storage. [120][121][122] More importantly, unlike Li and Na anodes, Mg anodes have no dendrites during long-term Mg plating and stripping, making MIBs an inherently high-security battery system. All these advantages make MIBs promising in the market of low-cost and sustainable energy storage equipment.…”

“…Because magnesium (Mg) metal not only is abundant in the ambient atmosphere, cheap and extremely safe but also has a volume capacity (3833 mAh cm −3 ) that is almost twice that of lithium (2046 mAh cm −3 ). Therefore, rechargeable magnesium ion batteries (MIBs) are very promising for large‐scale energy storage . More importantly, unlike Li and Na anodes, Mg anodes have no dendrites during long‐term Mg plating and stripping, making MIBs an inherently high‐security battery system.…”
