FE3O4 AND MN3O4 DECORATED ONTO N-DOPED GRAPHENE FOR ANODE ACTIVE MATERIALS IN LITHIUM-ION BATTERIES

Abstract

Recently, iron oxide (Fe3O4) and manganese oxide (Mn3O4)has been the most promising anode active materials in lithium-ion batteries (LIBs) owing to their abundance, low cost, and environmental friendliness. However, these batteries have many disadvantages, hindering the application of Fe3O4 and Mn3O4 as anode materials. This study aimed to decorate Fe3O4 and Mn3O4 onto pristine N-doped graphene and improve their electrical properties for potential use as enhanced active anode materials for lithium-ion batteries. We synthesized Fe3O4 and Mn3O4 via the simple co-precipitation method, and the result shows that the oxides were decorated onto N-doped graphene nanosheets that were further confirmed by SEM, XRD, TEM, and EDX analysis. The electrical conductivity analysis proved that the additional Fe3O4 and Mn3O4 play an important role in improving pristine N-doped graphene. This finding also suggests that Fe3O4 and Mn3O4 are potentially active anode materials in LIBs' applications.
