摘要
Co-doped LiMn2O4 octahedral particles were prepared by the rheological phase reaction using LiOH center dot H2O, electrolytic manganese dioxide (EMD), and Co3O4 as starting materials. The crystal structure and morphology of as-synthesized compound were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The XRD results showed that the obtained powders were single-phase with a cubic spinel structure (Fd3m space group). SEM micrograph revealed that the particles possessed an octahedral morphology, with an average particle size of about 1-2 mu m. Electrochemical test results showed that this Co-doped LiMn2O4 could deliver high specific capacity and good cycling stability, for the initial discharge capacity was 112.5 mAh g(-1) and the discharge capacity remained to keep 100 mAh g(-1) at 100th cycle, with an average capacity fade rate about 0.1 % per cycle.
