Summary:A method for recovering lithium battery slurry, the method comprising: pretreating lithium battery slurry, and then subjecting the pretreated lithium battery slurry to centrifugal spray drying to separate a solid phase and a solvent. A device for the recovery of lithium battery slurry is a centrifugal spray drying system, and comprises a spray chamber (100), a cyclone separator (200), a condenser (400), a condensate storage tank (500), and a rectification tower (600); the system improves upon original centrifugal spray drying devices, and is designed to combine the processes of centrifugal spray drying and NMP condensation recovery, such that NMP can be directly recovered after separation of positive electrode material and the NMP.
