| Research Abstract |
We investigated structural features and electrochemical properties of iron oxide produced by iron-oxidizing bacteria. This material has a unique nano-and micro-architectural structure : the structure is primarily composed of 3-nm-nanoparticles and these primary particles are mildly aggregated to form secondary particles with several tens of nanometer and these secondary particles are finally aggregated to form microtubules~ 1μm in diameter. This natural nanometric iron oxide has a very large capacity and excellent cyclability and rate capability for Li-ion battery electrode.
