▎ 摘　　要

A MnFe2O4-reduced graphene oxide (rGO) nanocomposite was successfully synthesized by a one-pot low-temperature process by coprecipitation of Mn ions produced in the modified Hummer's method and in situ reduction of GO at 90 degrees C. It exhibited excellent electrochemical performance, retaining a reversible capacity of 581.2 mAh g(-1), about 70% of the theoretical capacity, at a specific current of 1 A g(-1) after 200 cycles.
