• We measured impedance spectra for lithium-ion batteries with a large capacity over 10 Ah and a small capacity under 1 Ah. We assigned the impedance spectra to the electrochemical parameters for the positive and negative electrode interfaces without disassembling. We proposed an advanced impedance analysis technique with constant phase element normalized by battery capacity for lithium-ion batteries of 10 Ah-class.
