Abstract

The invention discloses a high-efficiency separation and recovery process for lithium batteries, comprising: step 1, classifying the collected waste lithium batteries in shape; step 2, using a lithium battery shell separation device to remove the shell of the lithium battery; step 3, using a collector to collect Shell fragments and battery pole cores falling from the lithium battery shell separation device; step 4, use a vibrating screen device to filter the shell fragments and battery pole cores to complete the separation and recovery of shell materials and battery pole cores. The invention first classifies the collected waste lithium batteries by shape, classifies the cylindrical lithium batteries, and performs special separation on the cylindrical lithium batteries to improve the efficiency of separation and recovery. Secondly, the lithium battery casing is vertically cut and obliquely cut using the lithium battery casing separation device, so that the lithium battery casing forms a sheet shape, which facilitates the separation of the lithium battery casing and the battery pole core, reduces the difficulty of later recycling, and improves the efficiency of separation and recycling. efficiency.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, and more specifically, the invention relates to a high-efficiency separation and recovery process for lithium batteries. Background technique [0002] With the development of electronic technology and new energy technology, the application of digital electronic products and new energy vehicles is becoming more and more common. Lithium batteries are important energy supply components for digital electronic products and new energy vehicles. The demand is very large, and after use There are also more and more discarded lithium batteries. These waste lithium batteries are under increasing pressure on environmental protection, how to quickly and reasonably recycle waste lithium batteries has become an urgent problem to be solved. [0003] Lithium batteries generally include a casing and a battery pole core, wherein the battery pole core is formed by winding a combination of positive electro...
