| titleOfInvention | Cobalt metal recovery method and device for lithium ion battery waste |
| abstract | The invention discloses a cobalt metal recovery method and equipment for lithium ion battery waste; the recovery method comprises the following steps: mixing solid waste with an alkali metal solution, fully reacting, and chelating to form a cobalt-organic matter intermediate; secondly, performing solid-liquid separation on the mixture of the solution containing the cobalt-organic matter intermediate and the solid; step three, carrying out hydrothermal reaction on the solution containing the cobalt-organic matter intermediate to crystallize cobalt hydroxide powder; the solid waste in the step one is waste containing cobalt element in the lithium ion battery, and is subjected to crushing and drying pretreatment when being mixed with an alkali metal solution; and (3) during solid-liquid separation in the second step, washing the surface of the solid with water and/or alcohol. In the closed system, the alkali metal solution is used for reacting with the solid mixture to extract the cobalt element, the reaction condition is mild, the waste is not discharged to the external environment, the solvent in the reaction can be recycled, the reaction is fast, the cost is low, and the method is a simple and energy-saving method for effectively recycling the cobalt element in the lithium battery. |
