Abstract

See full text

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.
