[0029] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0030] see figure 1 , shown in the figure is a recycling method for scrapped ternary lithium batteries, including the following steps:
[0031] Step S1, dismantling the scrapped ternary lithium battery into lithium battery cells, and discharging the disassembled lithium battery cells. In this embodiment, the disassembled lithium battery cells are soaked in salt water for discharge treatment, and the discharged lithium battery cells are cleaned to remove the soaking liquid attached to the surface of the lithium battery cells.
[0032] Step S2, in the state of using an inert gas as a protective gas to protect the discharged lithium battery cells, so that the lithium battery cells are crushed to form battery crushed slurry. In this embodiment, th...
