Synthesis of Metal Oxides/Graphene Nanocomposites for Applications in Lithium-Ion Battery
In this report, we employed graphene and graphene-based composite material as anode materials for lithium-ion battery to improve their performance. Stannic oxide (SnO2), cobalt oxide (Co3O4), and vanadium pentoxide (V2O5) were synthesized respectively on graphene surfaces. The incorporation of metal oxides can further improve electron mobility of graphene and lithium-ion battery charge/ discharge stability. The performance of lithium-ion batteries was tested by charge-discharge experiments, and their charge-discharge current density, charge-discharge voltages, charging rate, and cycle stability were measured and discussed.
