Researchers create rGO/MOS2 nanoflower cathodes for aluminum-ion batteries

Researchers from China’s Jiangnan University and Dalian University of Technology have designed MoS2/rGO nanoflowers as cathodes for aluminum-ion batteries (AIBs).

Aluminum-ion batteries (AIBs) show promise thanks to their high aluminum reserves, high theoretical specific capacity, and high safety. However, their actual capacity is far lower than the real capacity due to the limitation of cathode. The team’s new strategy utilizes reduced graphene oxide-intercalated MoS2 nanoflowers for AIB cathodes, via a hydrothermal method. This approach promoted the transition of MoS2 crystal phase from 2H to 1 T, and the expansion of interlayer spacing from 0.62 nm to 1.03 nm, overcoming the shortcomings of slow electrochemical reaction kinetics and low capacity caused by the outstanding semiconductor properties of 2H MoS2 and the compact interlayers.
