Abstract

Electrochemical impedance spectroscopy (EIS) is an effective method to characterize electrochemical electrodes, and is potentially a solution for estimating the state of health (SOH) of lithium-ion batteries (LIBs). A time domain EIS measurement technique followed by an equivalent circuit model interpretation is proposed in this paper. The accuracy of the measurement and the EIS-based SOH estimation are validated on Sanyo's UR14500P type LiCoO2 cells, the results of which show that the proposed methods are effective in fast and economical assessment of LIBs.
