摘要：
In the current work, electrochemical impedance spectroscopy is applied to lithium batteries with different power size, shape and technology in order to monitor the slate of health of the cells. The employed approach shows that the frequency analysis can provide the aging state evaluation. This is particularly evident for a narrow frequency range, and even a single frequency readout can be exploited to quickly and reliably evaluate the state of health of the cell. Therefore, the presented method results promising for many practical applications, such as for battery management strategies and cell monitoring purposes.
