Abstract
A process and a device for recycling waste lithium battery materials are provided. The process includes: S. charging, transporting composite pole pieces to a flexible de-powdering device through a uniform feeder; S. flexibly removing powder, rubbing and beating the composite pole pieces using the flexible de-powdering device, after flexible depowdering, discharging part of composite current collectors from a closed air spiral discharge pipe connecting to the flexible de-powdering device; S. centrally receiving materials, transporting falling electrode powder and remaining composite current collectors to a cyclone collector through negative pressure pipelines, and centrally collecting dust produced in the process of uniform feeding and closed air spiral discharge; and S. screening, screening and separating the materials collected by the cyclone collector using a vibrating screen, and separating the composite current collectors and electrode powder. The process can improve the separation efficiency of the electrode powder.
