The PUHLER Cycle "Waste Lithium ion Battery Crushing, Sorting and Recycling System" considers the safety and environmental protection process of lithium battery recycling, with the goal of resource regeneration and intelligent efficiency. It adopts the "flexible feeding charged crushing medium and low temperature heat treatment full component physical sorting" process, effectively solving problems such as long load discharge cycle, high cost, water pollution caused by brine discharge, and explosion during the crushing process. It has overcome industry technical difficulties such as incomplete stripping of positive and negative electrode powder, high copper and aluminum content in electrode powder, and fluoride pollution.
