Abstract

3D flower-like NiCo ₂ O ₄ and NiCo ₂ O ₄ @MnO ₂ were successfully synthesized via a hydrothermal method. Scanning electron microscopy results illustrated that NiCo ₂ O ₄ is formed by stacking nanosheets, and after reaction in KMnO ₄ solution, MnO ₂ were evenly coated on the surface of NiCo ₂ O ₄ formed flower-like structure. The as-synthesized materials were evaluated as an anode materials for lithium-ion batteries, NiCo ₂ O ₄ and NiCo ₂ O ₄ @MnO ₂ exhibited high specific capacities of 841.9 and 1 000 mA h g ⁻¹ after 100 cycles respectively. Moreover, NiCo ₂ O ₄ @MnO ₂ composites demonstrate good rate performance. These enhanced electrochemical properties could be attributed to the distinctive 3D flower-like structure, which increases the contact area between the electrolyte and electrode material to provide more active sites, and reduced volume effects during repeated insertion/extraction of lithium ions. The results suggest that the NiCo ₂ O ₄ @MnO ₂ composites could be promising LIBs anode materials.
