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 LiNi_1/2Mn_1/2O₂-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).
