Summary:Rechargeable magnesium batteries (RMBs) are promising devices for energy storage owing to their high volumetric energy density and high safety, but they still suffer from the lack of suitable cathodes. Herein, we report the development of ultrathin hydrated H 0.68 Ti 1.83 O 4 /reduced graphene oxide nanosheet composite (HTO/rGO) as a novel cathode for RMBs. The HTO/rGO, strongly combining ultrathin HTO nanosheets (5 nm in thickness with large interlayer spacing of 0.93 nm) and high electronic conductivity of rGO performs quick Mg 2+ kinetics with high reversibility and considerable capacity of 182 mA h g −1 , undergo an intercalation type reaction. Rechargeable magnesium batteries (RMBs) are promising devices for energy storage owing to their high volumetric energy density and high safety, but they still suffer from the lack of suitable cathodes.
