Zusammenfassung:	The present disclosure relates to methods for recovering metals from used lithium-ion batteries and related electronic wastes. The methods provide modular, inexpensive, and energy efficient means for recovering up to 99.9% pure lithium, nickel, cobalt, and manganese in the form of various oxides or salts, e.g., phosphates, sulfates, or hydroxides. The methods produce nearly zero waste, as many of the recovered waste products can be purified and/or recycled. La présente divulgation concerne des procédés de récupération de métaux à partir de batteries au lithium-ion usagées et de déchets électroniques associés. Les procédés fournissent un moyen modulaire, peu coûteux et économe en énergie pour récupérer jusqu'à 99,9 % de lithium pur, de nickel, de cobalt et de manganèse sous la forme de divers oxydes ou sels, par exemple, de phosphates, de sulfates ou d'hydroxydes. Les procédés ne produisent presque aucun déchet, car de nombreux déchets récupérés peuvent être purifiés et/ou recyclés.
