Description

Technical Field

[0001] The utility model relates to the technical field of lithium ion batteries, in particular to a disassembly mechanism for recycling lithium ion batteries. Background Art

[0002] Lithium-ion battery is a secondary battery that mainly relies on the movement of lithium ions between the positive electrode and the negative electrode to work. During the charge and discharge process, Li+ is embedded and de-embedded between the two electrodes. When charging, Li+ is de-embedded from the positive electrode and embedded into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; when discharging, the opposite is true. Lithium batteries are divided into lithium batteries and lithium-ion batteries. Mobile phones and laptops use lithium-ion batteries, which are commonly referred to as lithium batteries. Batteries generally use materials containing lithium elements as electrodes and are the representative of modern high-performance batteries.

[0003] Since a lot of lithium-ion batteries are used in daily life, when recycling lithium-ion batteries, in order to protect the environment and prevent pollution, special disassembly mechanisms are needed to operate and reduce pollution to the environment.

[0004] After searching, it is proposed in a lithium-ion battery disassembly device with patent publication number CN220462483U that "by providing a clamping assembly that can clamp cylindrical batteries and square shell batteries, and a splitting assembly that can freely adjust the tool, it is suitable for the disassembly of square shell batteries and cylindrical batteries, which is convenient for operators to conduct tests. At the same time, its high applicability does not require the purchase of disassembly equipment dedicated to square shell batteries or cylindrical batteries, thereby reducing the equipment purchase cost";

[0005] However, the above solution still has certain shortcomings in actual use. The solution uses a cutter to disassemble and cut the lithium-ion battery, but no protective structure is set during the cutting process of the lithium-ion battery, resulting in the waste chips generated when the lithium-ion battery is cut to splash out, thereby polluting the working environment and threatening the personal safety of nearby workers.
