- Abstract
The SbFeO3 was reduced to obtain the SbFe and Sb2Fe alloys, and the SbGeO3.5 was reduced to obtain the Sb-Ge metal composite powder. The simulation lithium ion battery was prepared by using the SbFe and Sb2Fe alloys or the Sb-Ge metal composite powder as anode material. The analysis of the XRD and the SEM for the SbFe and Sb2Fe alloys and the Sb-Ge metal composite powder were completed, and the electrochemical properties of the simulation battery were characterized. The results indicate that the first discharge capacity and charge capacity were 510mAh/g and 475mAh/g, and its efficiency was 93.1% for the SbFe and Sb2Fe alloys. The first discharge capacity and charge capacity were 480mAh/g and 425mAh/g, and its efficiency was 88.5% for the Sb-Ge metal composite powder. The electric capacity gradually decreased with the charge-discharge cycle number increasing, and the discharge capacity and the charge capacity at 20th week corresponded to 70.6% and 73.7% of the initial discharge capacity and the charge capacity for the SbFe and Sb2Fe alloys as anode material, and the discharge capacity and the charge capacity at 20th week corresponded to 78.1% and 82.4% of the initial discharge capacity and the charge capacity for the Sb-Ge metal composite powder as anode material. Although the initial electrochemical capacity and the charge/discharge efficiency for the SbFe and Sb2Fe alloys were higher than those for the Sb-Ge metal composite powder, the irreversible capacity loss for the SbFe and Sb2Fe alloys was bigger than that for the Sb-Ge metal composite powder as anode material. The reaction mechanism for SbFe and Sb2Fe alloys or Sb-Ge composite powder with the Li was embedding/taking off lithium process. The SbFe and Sb2Fe alloys or the Sb-Ge metal composite powder has certain embedded/taking off lithium ability, thus can be used as the candidate material for the lithium ion battery anode active material.
