| Research Abstract |
Polarization behavior of lithium insertion materials for advanced lithium-ion batteries are examined. Steady-state polarization measurements revealed that polarization behavior of lithium insertion electrodes consists of resistance polarization only, i.e., linear relation between applied voltage and observed current. From the results obtained by polarization measurements of lithium insertion materials, one can estimate input- and output power for lithium-ion batteries. Steady-state polarization measurements also indicate that highly-crystallized materials shows superior property to the poorly-crystallized samples.
