Technical Field

[0001] The invention relates to the field of batteries, in particular to a portable electrolyte collection device. Background Art

[0002] With the development of the electric vehicle industry, the total amount of waste power batteries is increasing. The long-term stacking and disposal of waste power batteries will cause environmental pollution and safety hazards. The long-term stacking and disposal of waste power batteries is also a waste of resources. Waste power batteries contain a large number of metal element compounds. Making full use of these substances can reduce the mining of minerals, save a lot of resources, and also reduce the pollution and energy consumption caused by mining. The electrolyte in the waste battery will cause electrolyte pollution. The electrolyte solute LiPF6 is a toxic substance and is easy to deliquesce, which will cause fluorine pollution, and the solvent will cause water pollution. Therefore, it is very important to recycle the electrolyte in waste batteries.

[0003] However, the electrolyte recovery device in the prior art is huge and heavy, and the battery disassembly requires a special workshop to operate. It is difficult for outdoor maintenance operations or small repair shops to recover the electrolyte, which makes it easy for the electrolyte to leak when the battery is disassembled, causing pollution accidents. Summary of the invention

[0004] The technical problem that this application aims to solve is to provide a portable electrolyte collection device that can temporarily store electrolyte. When technicians perform outdoor maintenance work or small repair shops disassemble and assemble batteries, the electrolyte in the battery can be temporarily stored in the portable electrolyte collection device, avoiding pollution accidents caused by electrolyte leakage.
