Preparation and Lithium Storage Performances of Porous Co₃O₄ Nanorods

Abstract:

We report on the porous Co₃O₄ nanorods synthesized by hydrothermal reaction and applied as an anode material for reversible lithium storage. The Co₃O₄ with porous nanorods structure increases the contact surface, shortens the diffusion path of ion/electron, and improves its structure stability and collaborative electronic transmission. Due to the nanoparticle subunits, the electrodes exhibit high electrochemical performance. Impressively, a high reversible discharge specific capacity of 1105 mAh g^-1 is obtained at 200 mA g^-1 after 50 cycles. This indicates the excellent potential of porous Co₃O₄ nanorods as an anode material for lithium ion batteries. Thus, the porous Co₃O₄ nanorods might open an insight for transition-metal oxides as energy storage materials.
