  "textContent": "Disclosed in the present invention is a recovery process for a waste battery electrode sheet, the method comprising the following steps: subjecting a waste battery electrode sheet to shearing, drying and cold treatment, and then rolling and screening same to obtain a first positive electrode material and a first waste electrode sheet; subjecting the first waste electrode sheet to shearing, drying and cold treatment, and then rolling and screening same to obtain a second positive electrode material and a second waste electrode sheet; and roasting the first positive electrode material and the second positive electrode material to obtain a positive electrode powder. In the present invention, the aluminum content in the positive electrode material is reduced by means of step-by-step shearing, and the adhesion performance of a waste positive electrode plate binder is then reduced by means of vacuum freeze-drying and spraying with a quick-cooling agent. The aluminum foil of the positive electrode material does not easily break when being broken after vacuum freeze-drying, and the morphology and output of the aluminum foil after primary shearing and secondary shearing are basically unchanged.",
