Comparative Study of Fe_2O_3-Nanoloaded Carbon and Fe_2O_3-Nano/Carbon Mixed Composites for Iron-Air Battery Anodes

摘要

In order to identify the most suitable material for the Fe/air battery anode, two kinds of materials, Fe_2O_3-nanoloaded carbon and Fe_2O_3-nanomixed carbons, were prepared from various carbon materials. The Fe_2O_3-nanoloaded carbon was prepared by loading Fe_2O_3 on carbon by a chemical method, while the Fe_2O_3-nanomixed carbon was prepared by mixing Fe_2O_3-nanopowder and carbon. The effect of various carbons on the electrochemical properties of both materials was investigated and compared. The results indicated that the Fe_2O_3-nanoloaded carbon is a promising material for the air-battery anode. Among the carbons used for the Fe_2O_3-nanoloaded carbon, graphite, and several nanocarbons exhibited improved characteristics.
