Layered H0.68Ti1.83O4/reduced graphene oxide nanosheets as a novel cathode for rechargeable magnesium batteries

Abstract

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 H0.68Ti1.83O4/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 Mg2+ kinetics with high reversibility and considerable capacity of 182 mA h gāˆ’1, undergo an intercalation type reaction.
