▎ 摘　　要

Reduced graphene oxide (rGO)-encapsulated MnGeO3 microspheres have been yielded via a facile, scalable and environmentally friendly route. Hydrothermal method was utilized to recrystallize MnGeO3 particles and form rGO encapsulation. Such rationally designed rGO-encapsulated MnGeO3 microspheres afforded excellent electrochemical performances, i.e. high first discharge capacity of 1364 mAh g(-1) and charge capacity of 810.8 mAh g(-1), and reversible capacity of 624.6 mAh g(-1) after 50 cycles at a current density of 200 mA g(-1) when they were employed as anode materials for Li ion batteries. These advantageous attributes make rGO-encapsulated MnGeO3 microspheres the potential anode materials for Li-ion batteries. (C) 2017 Elsevier B.V. All rights reserved.
