METHOD FOR RECOVERING METAL FROM LITHIUM-ION BATTERY WASTE

Title:

METHOD FOR RECOVERING METAL FROM LITHIUM-ION BATTERY WASTE

Document Type and Number:

Japanese Patent JP2023100249

Kind Code:

A

Abstract:

To provide a method for efficiently recovering metal from lithium-ion battery waste by reducing the use of sodium hydroxide as a pH adjuster.SOLUTION: A method for recovering metal from lithium ion battery waste includes a wet process for using acid to leach metal including lithium in the lithium ion battery waste and extracting the metal from the metal-containing solution in which the metal is dissolved, where the lithium extracted in the wet process is used as a pH adjuster used in the wet process.SELECTED DRAWING: Figure 1
