Transition metal dichalcogenide‐based materials for rechargeable aluminum‐ion batteries: A mini‐review

Abstract

Rechargeable aluminum‐ion batteries (AIBs) have emerged as a promising candidate for energy storage applications and have been extensively investigated over the past few years. Due to their high theoretical capacity, nature of abundance, and high safety, AIBs can be considered an alternative to lithium‐ion batteries. However, the electrochemical performance of AIBs for large‐scale applications is still limited due to the poor selection of cathode materials. Transition metal dichalcogenides (TMDs) have been regarded as appropriate cathode materials for AIBs due to their wide layer spacing, large surface area, and distinct physiochemical characteristics. This mini‐review provides a succinct summary of recent research progress on TMD‐based cathode materials in non‐aqueous AIBs. The latest developments in 3D printing of 2D materials for AIBs are also discussed.

Insight into the Storage Mechanism of Sandwich-Like Molybdenum Disulphide/Carbon Nanofibers Composite in Aluminum-Ion Batteries

“…In 2015, Lin introduced a model of AIBs utilizing a novel ionic liquid (AlCl 3 /[EMIm]Cl) as the electrolyte, marking a significant breakthrough in the field of AIBs [ 8 ]. Subsequently, various materials have been integrated into the cathode materials of non-aqueous AIBs, including metal oxides (such as MnO 2 and V 2 O 5 ) [ 9 , 10 ], transition metal chalcogenides (such as CuS 2 , VS 2 , and Co 9 S 8 ) [ 11 , 12 , 13 ], carbon-based materials (such as graphene, graphitic carbon, and graphitic foam) [ 14 , 15 , 16 ], and other materials (such as MXenes and conducting polymers) [ 17 , 18 ]. Among them, carbon-based materials are one of the most used in AIBs, with advantages such as high discharge voltage and good cycle stability.…”
