The invention relates to a process 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, resulting in formation of a lithium sulfide containing solution from which insoluble components are removed by filtration, and the electrolyte is removed by phase separation, followed by a process for separation of the lithium from the lithium sulfide-containing solution.

The invention relates to a method for the hydrometallurgical recovery of lithium from the lithium manganese oxide-containing fraction of used galvanic cells.

Method for the hydrometallurgical recovery of lithium from the lithium manganese oxide-containing fraction of used galvanic cells

A method for the hydrometallurgical recovery of lithium from a lithium transition metal oxide containing fraction of used galvanic cells is disclosed. According to the method, the lithium transition metal oxide containing fraction is introduced into sulphuric acid or hydrochloric acid, and hydrogen peroxide is added in an amount that is at least stoichiometric relative to the transition metal content to be reduced of the lithium transition metal oxide-containing fraction.

A method for the hydrometallurgical recovery of lithium from the fraction of used galvanic cells containing lithium, iron and phosphate is disclosed. According to the method, lithium-iron-phosphate-containing fraction is introduced into sulfuric acid and/or hydrochloric acid, and hydrogen peroxide is added in an amount that is at least stoichiometric relative to the iron content to be oxidized of the lithium-iron-phosphate-containing fraction.
