US 2026/0216735 A1 · SYSTEM AND METHOD FOR SEGREGATION OF MATERIALS FROM SHREDDED LITHIUM-ION BATTERIES

Abstract

The various embodiments of the present invention provide a system and method for segregation of materials from shredded Lithium-ion batteries. The embodiments also provide an integrated mechanism to segregate metal, polymer and black-mass from shredded Lithium-ion batteries. The present invention provides a system for classification and segregation of shredded material from Lithium-ion batteries through agitation and density separation processes. The system is designed to perform three tasks in a sequential manner: firstly, to open up the layers of batteries i.e., to separate the layers of the different material; secondly, to separate the polymers and black-mass from the layers; and, thirdly to separate the foils of the batteries into low/high density material, suspension and by brittleness of material. The invention provides a system for an optimized separation and segregation of a plurality of materials from shredded Lithium-ion batteries.
