Abstract

Abstract: We report a novel in-situ symbiosis method to prepare reduced graphene oxide wrapped Mn3 O4 nanoparticles (rGO/Mn3 O4 ) with uniform size about 50 nm as anodes for lithium-ion batteries (LIBs), which can simplify the preparation process and effectively reduce pollution. The rGO/Mn3 O4 nanocomposite exhibited a reversible specific capacity of 795.5 mAh g −1 at 100 mA g −1 after 200 cycles (capacity retention: 87.4%), which benefits from the unique structural advantages and the synergistic effect of rGO and Mn3 O4 . The Mn3 O4 nanoparticles encapsulated among the rGO nanosheets exhibited good electrochemical activity, and the multilayer wrinkled rGO sheets provided a stable 3D conduction channel for Li + /e − transport. The rGO/Mn3 O4 nanocomposite is a promising anode candidate for advanced LIBs with excellent cycling performance and rate performance. Furthermore, this new preparation method can be extended to green and economical synthesis of advanced graphene/manganese-based nanocomposites.
