Description

Technical Field

[0001] The present application relates to the technical field of battery aluminum shell processing, and in particular to a battery aluminum shell punching mechanism. Background Art

[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] The lithium batteries currently on the market usually include a laminated structure, that is, the positive electrode sheet, the negative electrode sheet and the isolation membrane are stacked to form a battery core, and then a square aluminum shell is encapsulated outside the battery core. Since the 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. When recycling the battery cells, it is necessary to first cut along the edge of the top cover of the aluminum shell of the battery cell and separate the shell of the aluminum shell from the top cover, and then cut the protective polyester film around the battery cell inside the aluminum shell, and then unfold the battery cell inside the aluminum shell, and finally use a cutter to cut the electrode ear welding position 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, so as to facilitate the subsequent recycling of the battery cell.

[0004] However, when the existing cutter is used to cut the square aluminum shell, it is necessary to cut the connection between the shell and the top cover of the aluminum shell step by step. As a result, the cutter is prone to squeeze the internal battery cells during the cutting process, causing damage to the battery cells, affecting the subsequent recycling of the battery cells.
