Abstract

A novel three-dimensional (3D) porous structured Co₃O ₄ was prepared by electrodeposition combined with thermal-treatment method. The electrochemical properties of as-prepared 3D porous Co ₃O₄ were closely related to its morphology and structure which can be modified by various thermal-treatment temperatures. The 3D porous Co₃O₄ prepared at 300 °C exhibited smaller crystallite size and higher capacity compared to 400 °C as well as 500 °C. As used in lithium-ion batteries, the porous Co₃O₄ anodes delivered a high reversible capacity of about 1100 mAh g^-1 with no obvious capacity fading up to 50 cycles and exhibited higher rate capability compared with Co₃O₄ foil anodes. The enhanced electrochemical performances of 3D porous Co₃O₄ anodes are attributed to its unique 3D porous structure which can offer a large materials/electrolyte contact area and accommodate the strain induced by the volume change during cycling.
