Abstract

The invention discloses an efficient separation and recovery process for lithium batteries. The efficient separation and recovery process comprises the following steps: 1, classifying the shapes of collected waste lithium batteries; 2, removing the shell of the lithium battery by using a lithium battery shell separation device; 3, collecting shell fragments and battery pole cores falling from thelithium battery shell separation device by using a collector; and 4, filtering the shell fragments and the battery pole core by using a vibrating screen device to finish separation and recovery of theshell material and the battery pole core. According to the method, firstly, collected waste lithium batteries are subjected to shape classification to classify cylindrical lithium batteries, and thecylindrical lithium batteries are subjected to special separation, so that the separation and recovery efficiency is improved. And secondly, the lithium battery shell is vertically cut and beveled byutilizing the lithium battery shell separation device, so that the lithium battery shell is in a sheet shape, the lithium battery shell is conveniently separated from the battery pole core, the laterrecovery difficulty is reduced, and the separation and recovery efficiency is improved.

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...
