Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery recycling, in particular to a crusher for recycling waste lithium batteries. Background Art

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloys as positive / negative electrode materials and a non-aqueous electrolyte solution. Because they contain a large amount of high-value metals, used lithium batteries are disassembled and recycled. During the disassembly and crushing process of existing lithium batteries, the damage to the lithium batteries can cause the electrolyte inside to leak and come into contact with the positive and negative electrode materials inside the lithium battery, causing an internal short circuit and causing a fire, making the crushing process dangerous. At the same time, after the existing crushing device crushes the lithium battery, the electrolyte inside the lithium battery mixes with the solid material and the electrolyte, affecting subsequent recycling. For this reason, we propose a crusher for the recycling of used lithium batteries. Utility Model Content
