In-Situ Synthesis of Rgo/Mn3o4 Nanocomposite As Anode Materials for High-Performance Lithium-Ion Batteries

We report a green and facile method to prepare reduced graphene oxide wrapped Mn 3 O 4 nanoparticles (rGO/Mn 3 O 4 nanocomposite) as anodes for high-performance lithium-ion batteries, which can make full use of precursor materials, effectively reduce pollution and simplify the preparation process. The rGO/Mn 3 O 4 nanocomposite exhibited excellent electrochemical performance (with a reversible specific capacity of 795.5 mAh g -1 and a capacity retention rate of 87.4% at 100 mA g -1 after 200 cycles.) as compared with pure rGO and Mn 3 O 4 electrodes, benefitting from the unique structural advantages and the synergistic effect of Mn 3 O 4 and rGO. The rGO/Mn 3 O 4 nanocomposite has good corrosion resistance, high reversible specific capacity, excellent cycle performance and rate performance, it is a promising anode candidate material for high-performance lithium-ion batteries. Furthermore, this new synthesis method provides new ideas for the green and efficient synthesis of graphene/Mn-based composite materials.
