Description

technical field [0001] The invention relates to the technical field of recycling and processing of waste batteries, in particular to an automatic device for separating surface attachments of positive and negative electrodes of waste power lithium batteries. Background technique [0002] Since the 21st century, new energy vehicles have become one of the key development directions for countries all over the world to achieve energy conservation and emission reduction. By 2020, my country's annual output of new energy vehicles has reached 2 million, and the cumulative output has exceeded 5 million. The service life of power lithium batteries on electric vehicles is generally 5-8 years. After 2018, power lithium batteries on new energy vehicles will begin to enter the stage of large-scale retirement. [0003] If the decommissioned power lithium battery is not handled properly, it will cause great harm to the ecology. The power lithium battery is mainly composed of positive elect...

Problems solved by technology

[0004] In the prior art, the separation between the surface layer of the waste battery pole piece and the battery pole piece is usually achieved by mechanical shock or impact after heating. Not only is the separation not sufficient and thorough, but it will also cause deformation or damage to the battery pole piece itself. The recycling of battery pole pieces is inconvenient; and the particle size of the separated surface matter is uneven, with large individual differences. Further grinding and crushing is required to achieve subsequent separation between different components in the surface matter, which increases the Labor Amount of Separation Work

At present, the recycling technology used in the battery recycling industry generally has problems such as low recycling purity, large dust in the working environment, and difficult operation for workers. Therefore, there is an urgent need for an automatic device that separates the surface attachments of the positive and negative electrodes of waste power lithium batteries to provide solutions. above question
