Abstract :

Li-excess positive electrode material (LiMO2-Li2MnO3 solid solution, M=Ni1/2Mn1/2 or Ni1/3Mn1/3Co1/3) is a good candidate as its high-capacity (250 mAh/g) and acceptable discharge voltage above 3.5 V for high energy-density lithium-ion battery to EV and PHEV application. Especially, LiNi1/2Mn1/2O2-Li2MnO3 solid solution (Li1+x(NiyMn1-y)1-xO2, 0

Biography :

Mitsuharu Tabuchi is an Inorganic Synthetic Chemist using wet-chemical process for oxide-based positive electrode material of lithium-ion battery. He has extensive experience in the synthetic construction to get homogeneous LiFeO2-Li2MnO3 solid solution. The constructed synthetic route is also effective for preparing LiNi1/2Mn1/2O2-Li2MnO3. He also has characterization experience using 57Fe Mössbauer Spectroscopy and X-ray Rietveld analysis to know the charge compensation mechanism for LiFeO2-Li2MnO3 system.
