Title:
SYSTEM AND METHOD FOR SEPARATION OF ACTIVE MATERIAL FROM LITHIUM-ION BATTERIES
Document Type and Number:
WIPO Patent Application WO/2023/148758
Kind Code:
A9
Abstract:
The various embodiments of the present invention provide a system and method for separation of active material from Lithium-ion batteries. The system comprises a fluid chamber, a shredder-crusher apparatus, a material inlet mechanism, a gas outlet mechanism and a material outlet mechanism. After a plurality of processes, the high-density material such as Aluminium, Copper, Iron etc. are separated by size classification. The liquid suspension is allowed to settle, and the water on the top and powder settled on the bottom are collected. The powder separated from suspension is deemed as black mass, and it comprises the active material from the Lithium-ion battery. The agitation tank breaks material introduced in it into smaller sizes in proportion to the brittleness. The material is then processed through a density separation, followed by wet-side classification to separate metals and active material, followed by dewatering.
