Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery electrolyte extraction, in particular to a waste lithium battery electrolyte separation and extraction 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 very 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. Lithium batteries need to be recycled after use. After the existing lithium batteries are recycled, they need to be crushed and decomposed, and then the electrolyte inside the lithium batteries is recycled and collected;

[0003] In Chinese utility model CN218686714U, a "device for separating and extracting electrolyte from waste lithium batteries" is proposed. When the device is used, the electrolyte is poured into a filter bin for filtration, and then the filtered electrolyte flows into a liquid storage tank. When the electrolyte is needed, it is only necessary to pull the pull ring to pull out the pull rod, and then use the pressure to extract part of the electrolyte in the liquid storage tank and flow it into the placement bucket. This avoids the need for general electrolytes to extract all the electrolytes after separation, making it impossible to perform a certain storage function and to facilitate quantitative sampling. Although the device improves the separation function of the electrolyte, since the device does not have a mechanism for crushing the waste batteries, electrolyte may still remain in the residue of the waste batteries during actual use, which results in the electrolyte failing to be fully separated, thereby virtually reducing the separation and extraction efficiency of the entire device.
