| Research Abstract |
Visualization of a phase boundary of intercalation cathodes for lithium-ion batteries was investigated by using in-situ micro-Raman spectroscopy. The movement of the phase boundary, which dominates the reaction rate for lithium-ion battery cathode, was evaluated quantitatively using this technique. The structural change of the cathode materials, such as a lithium cobalt oxide (LiCoO_2)and a lithium manganese oxide (LiMn_2O_4), was systematically investigated by in situ micro Raman spectroscopy.
