i5580, ABSTRACT from The studiedprocessdealsu.ith cobalt electrolyticrecoveryfrom Li-ion'batteries by means of both galvanostaticand potentiostatic electrowinning. The use of guluunortaticconditionsallows to obtain a good Co metal deposit,while potentiostatic óonditionsprovide a cobaltdepletionin the electrolyte.

The last operation is very interesting becausethe produced Co powd-er is transformedat lod .C in Co:oa precursorwith LizCo: for the Lithium Cobalt oxide cathodematerial.In this casewe havenot only a recoveryof Co but alsoa true recycleof the cathodeactivepaste.
