One-pot low-temperature synthesis of a MnFe2O4–graphene composite for lithium ion battery applications†
Abstract
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 °C. It exhibited excellent electrochemical performance, retaining a reversible capacity of 581.2 mA h g−1, about 70% of the theoretical capacity, at a specific current of 1 A g−1 after 200 cycles.
