Full-wet recovery process of waste lithium batteries

Abstract

The invention discloses a full-wet recovery process of waste lithium batteries. The full-wet recovery process comprises the following steps of wet charged crushing, direct leaching of battery scraps,in-situ impurity removal of leachate, deep impurity removal, material re-preparation and the like. The process can realize recovery of waste lithium ion batteries through a short process, and has theadvantages of high recovery rate of nickel, cobalt, manganese and lithium element, low equipment investment, small waste gas and waste water yield and the like.

Description

technical field

[0001] The invention relates to the technical field of battery recycling, in particular to a full wet recycling process for waste lithium batteries. Background technique

[0002] Lithium-ion batteries have been used more and more widely since they became commercially available in the early 1990s. Today, lithium-ion batteries are found in virtually everything from laptops and mobile phones to electric vehicles and energy storage devices. What followed was an alarming increase in the number of discarded lithium-ion batteries. The recycling of valuable resources in waste lithium batteries is of great significance both in terms of environmental protection and resource recycling. Some studies predict that by 2030, the global scrapped lithium-ion batteries will reach more than 11 million tons. Therefore, the recycling market of lithium-ion batteries has a bright future.

[0003] The current recycling of waste lithium batteries is mainly aimed at the recycling of...
