“…To solve the above problems, we must first understand more information about the electrochemical behavior of electrode materials during lithium delithiation/lithiation, including the performance of SEI and the charge transfer process at the electrode/electrolyte interface, which play a key role in cycle stability and capacity maintenance. EIS is one of the most effective instruments for researching the interface properties of electrode materials based on the delithiation/lithiation mechanism and has been confirmed before [20][21][22][23][24]. However, there are few studies on the failure mechanism of the electrode interface of Li-manganese-rich electrode materials in systematic EIS testing.…”

The nanoscale 0.5Li2MnO3·0.5Li(Ni0.44Mn0.44Co0.12)O2 Li-manganese-rich electrode material was synthesized by the co-precipitate method, and its electrochemical properties were systematically analyzed, especially the electrochemical impedance spectroscopy. The failure of the electrode interface and the structural transformation of the material at high potential are the main reasons for the deterioration of the Li-manganese-rich electrode, and high temperatures accelerate the deterioration. Based on the systematic analysis of the induced reactance change with electrode polarization potential, it is found that the induced reactance of a Li-manganese-rich electrode is not only related to the degree of delithiation/lithiation but also has a great relationship with the performance of the electrode/electrolyte interface. This conclusion is beneficial for the manufacturing of battery failure analysis by providing a theoretical basis for guidance.

Electrochemical impedance spectroscopy (EIS), a conventional and alternating‐current‐(AC)‐based technique for impedance measurement, is commonly used in battery diagnosis. However, it requires expensive equipment and demanding operating conditions and is complex and model‐dependent in data analysis. Recently, novel direct current (DC) analytics have emerged as an alternative to EIS. They are simple yet powerful, being capable of revealing impedance information that traditionally could only be obtained through EIS and determining Li‐ion diffusion coefficient. Besides, a complete EIS spectrum can be predicted based on constant current charging curves in the support of machine learning methods. This work highlights the similarities and discrepancies between DC techniques and EIS in the electrochemical analysis of Liion batteries. Looking ahead, DC techniques may be a promising substitute for EIS in future battery diagnosis, requiring simplified equipment while offering a deep understanding of battery impedance and its underlying electrochemical processes.
