Electrochemical impedance spectroscopy (EIS) is a powerful and non-invasive method of measuring the LICs impedance behavior over a wide frequency rang. When using EIS, a properly designed equivalent circuit model (ECM) of LICs is necessary.
Therefore, accurate detection of lithium plating is crucial for the health management and charging control of lithium-ion batteries. In this paper, an impedance-based method is proposed to detect lithium plating of lithium-ion battery by comparing the normalized charing internal resistance profiles.
Impedance equivalent circuit model of LICs is established. The impedance characteristics of LICs are analyzed with various U ocv and cycle numbers. As important electrochemical power storage technology, lithium-ion capacitors (LICs) combine the advantages of both electric double layer capacitors (EDLCs) and lithium-ion batteries (LIBs).
Among innovative electrochemical energy storage devices, lithium-ion capacitors (LICs) are receiving huge interest from both industry and academia. LICs are hybrid energy storage systems between electric double layer capacitors (EDLCs) and lithium-ion batteries (LIBs).
In this paper, battery lithium plating detection method based on charging internal resistance analysis was proposed. The key processing step was the normalization of the internal resistance curve. Firstly, the feasibility of the detection method is preliminarily verified by battery experiments and comparison with VRP.
Voltage relaxation coupled with EIS was employed to detect lithium plating. Two main features were observed in the EIS namely a decrease of the high frequency intersection resistance and a respective decrease in the diameter of the semicircle representing the anodic charge transfer process.
The proposed detection method is more sensitive and accurate and expected to detect lithium plating in real-time during the charging process. Finally, the model showed that the method remained effective and reliable for lithium plating detection when the charging conditions changed.
