Description

[0002] Lithium-ion battery is a secondary battery (rechargeable battery) that mainly relies on the movement of lithium ions between the positive and negative electrodes to work. Lithium-ion battery has the advantages of light weight, large capacity, and no memory effect, so it has been widely used. The widespread use of lithium batteries often produces a large number of waste batteries. In order to achieve the comprehensive utilization of waste resources, aluminum foil, as an important component of the battery, has a high recycling value and often needs to be recycled and reused.

[0003] At present, there are still certain shortcomings in the recycling process of lithium battery aluminum shells. During the tearing process of the aluminum surface, the unreasonable design of the existing combination unit can easily cause scratches, deformation and other damages on the aluminum surface. When tearing the aluminum surface, the contact pressure between the clamping jaws and the aluminum surface is too large, which will cause obvious indentations on the aluminum surface. In addition, during the separation process of the aluminum surface and the battery core, the separation is prone to incomplete. Part of the aluminum surface may stick to the battery core, making subsequent processing difficult and inconvenient for the effective recycling of waste lithium batteries.
