Impedance analysis of lithium systems

Impedance Spectroscopy as a Nondestructive Health Interrogation Tool for Lithium‐BCX Cells

“…Impedance spectroscopy (IS) has proved to be a powerful method for understanding interphase processes 24 and for characterizing the passive film which forms on the lithium electrode in primary batteries. [25][26][27][28] Using IS, Kuryakov et al 29 studied the growth of the solid electrolyte film on a lithium anode as a function of storage time in SOC12 electrolyte. The film thickness on the anode exposed to the electrolyte for 125 days was calculated from the resistance of the solid electrolyte film and was determined to be 440 nm.…”
