    • Provided is a method for recovering metal from a waste battery. The method for recovering metal from a waste battery comprises separating electrodes from a waste battery; extracting metal ions to be recovered from the electrodes; combining the metal ions in an extracting solution with a first electrode while dipping the first electrode and a second electrode in the extracting solution, wherein the first electrode includes the metal to be recovered and the second electrode includes a different metal from the metal to be recovered; charging the first and second electrodes to separate the metal ions from the first electrode while dipping the first and second electrodes in a different concentrate from the extracting solution; and recovering the metal from the concentrate. Accordingly, the method is capable of improving efficiency and lowering harmfulness in a metal recovery process.
    • 提供了从废电池中回收金属的方法。 从废电池回收金属的方法包括从废电池中分离电极; 提取要从电极回收的金属离子; 将提取溶液中的金属离子与第一电极组合,同时将第一电极和第二电极浸入提取溶液中,其中第一电极包括要回收的金属,第二电极包括与要回收的金属不同的金属 ; 对第一和​​第二电极进行充电以将金属离子与第一电极分离,同时将第一和第二电极浸入与提取溶液不同的浓缩液中; 并从浓缩物中回收金属。 因此,该方法能够提高金属回收工序的效率,降低有害性。
