METHOD FOR RECYCLING LI-ION BATTERIES

A method for recycling a battery including the following steps: a) dissolution of a battery waste, for example an electrode, including lithium and a metal selected from cobalt and manganese, such that a solution to be treated containing lithium ions and metal ions is formed, b) addition of a peroxym...

Zusammenfassung:	A method for recycling a battery including the following steps: a) dissolution of a battery waste, for example an electrode, including lithium and a metal selected from cobalt and manganese, such that a solution to be treated containing lithium ions and metal ions is formed, b) addition of a peroxymonosulfate salt to the solution to be treated, the solution to be treated being regulated at a pH ranging from 1 to 4 when the metal is cobalt or at a pH ranging from 0.1 to 2.5 when the metal is manganese, such that the metal ions are selectively precipitated in the form of metal oxyhydroxide, c) separation of the lithium ions from the solution to be treated. Advantageously, the solution further comprises nickel ions.
