Description

Technical Field

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive / negative electrode materials and non-aqueous electrolyte solutions. Due to the highly active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become mainstream.

[0003] Since existing lithium battery cells contain many harmful substances, such as heavy metals and toxic compounds, which will have a serious impact on the environment and human health, it is necessary to recycle the battery cells in a timely manner. At present, when recycling battery cells, it is necessary to first cut off the aluminum shell of the battery cell, then cut open the protective polyester film outside the battery cell inside the aluminum shell, then unfold the battery cell inside the aluminum shell, and finally use a cutter to cut the welding position of the pole ear between the battery cell and the top cover of the aluminum shell, so as to achieve complete separation between the battery cell and the aluminum shell.

[0004] However, when the existing cutter cuts the tabs on the top cover of the aluminum shell, the vibration of the cutter causes relative displacement between the aluminum shell and the battery cell, which makes it easy for the cutter to touch the battery cell during the cutting process and cause damage to the battery cell, affecting the subsequent recycling and reuse of the battery cell.
