| Research Abstract |
We studied the discharge-charge properties of Li+ ions of nanometric amorphous iron oxide of bacterial origin for use as Li-ion battery cathode. This material was found to have the unique nanostructure. The iron oxide showed excellent cycle characteristics in a voltage range of 1.5-4.0 V at high current rate. X-ray absorption fine structure measurement revealed that the Fe3+ Fe2+ reaction is predominant in these discharge-charge processes.
