The invention discloses an electrolytic stripping treatment method for positive pole materials of waste lithium batteries. The method comprises the following steps of: stripping aluminum foil in the positive pole materials of the lithium batteries through electrolysis with low current density or high current density, thus obtaining leaching solution containing a positive active substance, lithium cobalt, wherein during the electrolysis, the positive pole materials containing the aluminum foil of the waste lithium batteries are taken as cathodes and platinum electrodes of the waste lithium batteries are taken as anodes in sulfuric acid solution. The method is characterized in that when the electrolysis is performed at the low current density, positive pole powder is dissolved in electrolyte, and after the dissolution is finished, the aluminum foil is stripped, and the leaching solution containing the lithium cobalt is obtained; or when the electrolysis is performed at the high current density, the aluminum foil in which the positive pole powder is stripped is obtained, the positive pole powder is collected and is dissolved in the leaching solution containing the lithium cobalt from the electrolyte; and the low current density is 100-500 A/m<2>, and the high current density is 600-1,000 A/m<2>. The method has the advantages of simple process flow, low acid concentration, short leaching time and low treatment cost.
