[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. Lithium batteries themselves have a certain service life and will be recycled after the end of their service life. When waste batteries are processed, the battery shell and the harmful chemicals inside are separated, and the separated plastic shell is usually discarded. However, the waste plastic shell of the battery usually also has metal terminals, which are generally made of copper materials. Directly discarding them will also cause a waste of resources. Therefore, in view of the current situation, it is necessary to design a waste lithium battery shell crushing and screening device to separate and recycle the plastic shell and the metal terminal, so as to achieve the purpose of saving resources.

[0003] (1) The battery casing cannot be sufficiently crushed to separate the plastic from the metal.

[0004] (2) Plastics and metals cannot be recycled separately. Utility Model Content
