Zusammenfassung:	A method for evaluating the electrolyte resistance of an aluminum-plastic compound film. The method comprises the steps of: (1) providing an aluminum foil with a bright surface and a matte surface, coating a passivation solution on the bright surface of the aluminum foil, and then baking same after coating to complete the passivation treatment of the aluminum foil; (2) soaking the aluminum foil in an electrolyte, wherein the electrolyte comprises an organic solvent and lithium hexafluorophosphate; (3) placing the aluminum foil in an oven for baking, then taking out the aluminum foil, and cooling, cleaning and wiping same; and (4) testing the content of fluorine of the surface of the aluminum foil by means of energy spectrum analysis, and characterizing the electrolyte resistance of the aluminum-plastic compound film with the content of fluorine. In the technical solution of the present application, if the fluorine content of the surface of the passivated aluminum foil is high, it is illustrated that the elect
