Method and device for stripping and recycling active material of waste battery

The invention discloses a stripping method of a waste battery electrode plate. The method comprises the following steps: stripping a mixed system containing a waste battery electrode plate and a water-containing solvent under the assistance of ultrasound and ozone, and separating a current collector and an electrode active material in the electrode plate. The invention also comprises a scheme for deeply removing impurities from the stripped electrode material. The battery positive electrode active material is subjected to alkali leaching aluminum removal, ozone shearing fluorine removal and residual electrolyte degradation to obtain the high-purity positive electrode active material. The cathode active material can achieve the purposes of deep copper removal and residual organic electrolyte removal through acid leaching copper removal and ozone oxidation. Fluorine-containing and lithium-containing solutions generated in the fluorine removal process are sheared, fluorine ions are converted into stable precipit
