In order to provide a basis for the establishment of the leakage fault diagnosis method of lithium-ion battery electrolyte, search the parameters closely related to battery leakage, electrolyte leakage fault simulation experiments were designed, DC impedance tests as well as electrochemical impedance spectra tests were performed on leaking batteries and normal batteries, and the kinetic characteristics of the battery were analyzed based on the second-order equivalent circuit model parameters and the relaxation time distribution method. A set of DC impedance and AC impedance parameters to characterize the leakage fault was proposed, which provided a basis for the diagnosis of the leakage fault of lithium-ion batteries.
