Abstract (en)
[origin: WO2022208015A1] The invention relates to a method for dissolving a positive electrode material of a battery comprising a step during which the positive electrode material, comprising lithium and optionally cobalt and/or nickel, is submerged in an acid solution having a pH between 0 and 4, the acid solution containing either manganese ions or hydrogen peroxide, by means of which the lithium and optionally the cobalt and/or nickel is dissolved, and the manganese ions are selectively precipitated in the form of manganese oxyhydroxide.
