Influence of the Synthesis Route on the Properties of Hybrid NiO–MnCo2O4–Ni6MnO8 Anode Materials and their Electrochemical Performances

Graphical Spray pyrolysis and a solvothermal method were used to prepare two types of NiO–MnCo 2 O 4 –Ni 6 MnO 8 hybrid anode materials to compare their physical and electrochemical properties. The samples had similar hierarchical nanostructures, but that prepared by the solvothermal method had a smaller and more uniform particle size and larger BET surface area whereas those prepared by spray pyrolysis exhibited more regular morphology and more stable surface chemical states. New materials with different morphologies, nanostructures, and components can have structural advantages for application in materials science. Multicomponent-active hybrid nanostructured materials are among the best candidates for application in electrode materials. Spray pyrolysis and solvothermal synthesis are two popular methods for the preparation of multicomponent-active hybrid nanostructured materials. In this study, the two types of NiO-MnCo 2 O 4 -Ni 6 MnO 8 hybrid anode materials for use in lithium-ion batteries were synthesized by two different methods (spray pyrolysis and solvothermal synthesis), and the differences in their physical and electrochemical properties were compared. The two types of anode material exhibited the same hierarchical hybrid composition, but some different physical characteristics, which affected their electrochemical performance.
