We have found, first in the world, that we can make the transition process from kinetic state to equilibrium state of electrode material clear by analyzing it just after the Li insertion or extraction with time and we named this "Relaxation analysis". The Relaxation analysis is a revolutionary method to make the dynamic change of state clear for the electrode material and is important for research of electrode material. We have applied the Relaxation analysis to many kind of electrode material and it was revealed that every electrode material changes dynamically in its structures and/or phases according to the condition of Li transfer. The Relaxation analysis will develop as the powerful method for analyzing electrode materials.
