In this mini-review, the basic principles of EIS and the process of constructing a meaningful equivalent circuit model for lithium-ion batteries are introduced. Then, practical applications of EIS for understanding lithium-ion battery systems are explained.
The battery impedance spectrum provides valuable insights into battery degradation analysis and health prognosis [148], including the formation of the SEI film [77], the loss of active lithium and electrolyte [149], and the deterioration of the anode and cathode active materials [150].
Furthermore, the dependency of the lithium-ion battery impedance on the short-time previous history is shown for the first time for a new and aged cell. The influence of the measured dependencies of the battery impedance on potential applications is discussed.
It varies slightly with the SoC and considerably with the temperature, and it also changes during the battery lifetime. Furthermore, the dependency of the lithium-ion battery impedance on the short-time previous history is shown for the first time for a new and aged cell.
Figure 1 shows the impedance spectroscopy of a lithium-ion battery at 50% SOC and ambient temperature if 0 °C. The measurement frequency ranges from 0.01 Hz to 10 kHz. Obviously, the whole impedance spectroscopy consists of three main regions: the low-frequency region, middle-frequency region and high-frequency region [ 9 ].
As the temperature exceeds 10 °C, the impedance arc is mainly unaffected by the current amplitude. To reveal the impact of alternating current (AC) amplitude on impedance, this paper mainly investigates the effect of AC amplitude on the impedance characteristics of lithium-ion batteries with different SOCs (0.2, 0.5, 0.8) at 25 °C and −10 °C.
