Study on Correlation with SOH and EIS Model of Li-ion Battery

摘要：

Electrochemical impedance spectroscopy as an experiment method is adopted in this research. Combining the experiment of the lithium ion batterys cycle life span, the measure is done to get the SOH of the lithium ion battery by definition. Measure the electrochemical impedance spectroscopy of battery through electrochemical instrument and get the data of impedance by the impedance spectroscopy data which is got and analyzed by the special electrochemical software Zsimpwin, then the impedance model parameters can be obtained. According to the experimental results, study on the correlation between lithium ion batterys impedance and its SOH.
