A method for recovering valuable metals in cathode materials of decommissioned lithium-ion batteries |
| abstract |
The invention belongs to the technical field of recycling lithium ion batteries from electronic waste, and more particularly relates to a method for recycling valuable metals in positive electrode materials of decommissioned lithium ion batteries. It is a method for recovering metals in cathode materials of decommissioned lithium ion batteries by using oxidants and organic acids. Under subcritical conditions, the free radicals generated by the activation of oxidant persulfate or aqueous hydrogen peroxide solution are used to accelerate the destruction of the crystal structure of cathode materials of decommissioned lithium ion batteries. , and combined with the complexing effect of organic acids and reducing agents to promote the conversion of valuable metals into soluble states. The invention utilizes a green and safe method, uses the decommissioned lithium ion battery positive electrode material as a raw material, uses the free radicals generated by persulfate activation under subcritical conditions to destroy the crystal structure in the retired lithium ion battery positive electrode material, and can realize valuable The high-efficiency recovery of metal resources and the avoidance of secondary pollution to the environment have the advantages of low cost, simple process, easy to expand production and realize industrialization. |
