PROCÉDÉ DE DISSOLUTION D'UN COMPOSÉ DE LITHIUM, PROCÉDÉ DE PRODUCTION DE CARBONATE DE LITHIUM, ET PROCÉDÉ DE RÉCUPÉRATION DE LITHIUM À PARTIR DE DÉCHETS DE PILES SECONDAIRES AU LITHIUM-ION

摘要

A method for dissolving a lithium compound according to the present invention includes bringing a lithium compound into contact with water or an acidic solution, and feeding, separately from the lithium compound, a carbonate ion to the water or the acidic solution to produce carbonic acid, and allowing the carbonic acid to react with the lithium compound to produce lithium hydrogen carbonate.
