Beschreibung
Zusammenfassung:	The invention relates to a method for recovering lithium from lithium-sulfur accumulators, wherein the accumulators are discharged, shredded, and pre-cleaned by sieves or screens to separate housing and electricity collector parts, the remaining material is dispersed in an aqueous medium, the insoluble components are removed by filtration and the electrolyte by phase separation, followed by a method for separating the lithium from the remaining filtrate.
