Abstract

Lithium-ion discharge/charge properties of a nanometric amorphous iron-based oxide material of bacterial origin, L-BIOX, in a voltage range of 1.5-4.0 V were studied. X-ray absorption fine structure measurements confirmed that Fe³⁺ Fe²⁺ reactions dominate in this voltage range. Cycle characteristics with a capacity exceeding 70 mAh/g at a current rate of 1670 mA/g are considerably higher than those achieved by known simple iron-oxides such as α-Fe₂O₃.
