Abstract[English]
A method for recycling lithium from an input material comprising lithium and one or more transition metals, comprising the steps of: contacting said input material with a leaching medium comprising an organic acid; leaching lithium from the input material to form a leachate comprising an organic lithium salt; and electrolytically converting the organic lithium salt into an inorganic lithium salt in an electrochemical cell.[French]
L'invention concerne une méthode de recyclage du lithium à partir d'un matériau d'entrée comprenant du lithium et un ou plusieurs métaux de transition, comprenant les étapes consistant à : mettre en contact ledit matériau d'entrée avec un milieu de lixiviation comprenant un acide organique ; lixivier le lithium du matériau d'entrée pour former un lixiviat comprenant un sel de lithium organique ; et convertir électrolytiquement le sel de lithium organique en un sel de lithium inorganique dans une cellule électrochimique.
