Nanorod Mn3O4 anchored on graphene nanosheet as anode of lithium ion batteries with enhanced reversible capacity and cyclic performance

Abstract Nanorod Mn 3 O 4 anchored on graphene nanosheet (Mn 3 O 4 @GNS) using GNSs and MnSO 4 ·H 2 O as precursor materials have been prepared by a simple, effective and scalable method. The nanorod Mn 3 O 4 @GNS as anode materials in lithium-ion batteries exhibits the better electrochemical properties in the composite than the bare nanorod Mn 3 O 4 owing to its special structure, including a maximum reversible specific capacity of 1155.2 mA h g −1 at 100 mA g −1 , and the extraordinary cycling stability, with no decay in capacity for up to 100 cycles. The nanorod Mn 3 O 4 @GNS could be a promising candidate material for high reversible specific capacity, stable columbic efficiency, long cycle life and outstanding rate capacity. This study would offer a new method to improve the properties of insulating materials, holding a promising potential for high-performance lithium-ion batteries in energy storage fields.
