Biography

Mitsuharu Tabuchi is an inorganic synthetic chemist using wet-chemical process for oxide-based positive electrode material of lithium-ion battery. His synthetic experiences above 15 years were constructed mainly to get homogeneous LiFeO2-Li2MnO3 solid solution. The constructed synthetic route is also effective for preparing LiNi1/2Mn1/2O2-Li2MnO3 one. He has also characterization experience using 57Fe Mössbauer spectroscopy and X-ray Rietveld analysis to know charge compensation mechanism for LiFeO2-Li2MnO3 system. He found also Fe and Ni substituted Li2MnO3 and it has high-potential for practical use, because it can be prepared largely by chemical company (Tanaka Chemical Corporation) and then is electrochemically tested by battery manufacturer (NEC Corporation) as power-source of electronic vehicle (EV).
