Abstract Development of new power anode material with both high capacity and high-rate capability for lithium-ion batteries is highly desired. In this paper, a novel soft carbon anode for rechargeable lithium-ion batteries was developed using coal-based mesophase pitch. The structures of the materials were characterized by X-ray diffraction (XRD), Raman, N2 adsorption–desorption, Scanning Electron Microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). The electrochemical characteristics of the new anode material were investigated. It was found that the soft carbon anode from coal-based mesophase pitch carbonized under vacuum conditions can deliver higher energy density and higher rate capability compared to soft carbon carbonized under a nitrogen atmosphere. The enhanced electrochemical properties are attributed to smaller nanocrystallites, more porosity, defects and carbon species of the resulting anode material.

Ordered Macroporous

Three-dimensional ordered macroporous (3DOM) nickel ferrite ( NiFe2O4 ) anode material is synthesized via colloidal crystal template. A Close-packed poly(methyl methacrylate) (PMMA) spheres is used as template. Scanning electron microscopy observations reveal that the obtained 3DOM NiFe2O4 material has uniform spherical macropores with diameter about 140-nm and 20-nm size walls. The cyclic voltammogram and galvanostatic test are employed to evaluate the electrochemical characteristics of the as-prepared NiFe2O4 . It shows high initial discharge capacity (up to 1370 mAh g-1) and reversible capacity of 670 mAh g-1 at the current density of 0.2 mA cm-2. The results suggest that 3DOM nickel ferrite is a good candidate for anode material of lithium ion batteries.
