Electrolyte is the main component of lithium battery electrolyte. It plays an important role in conducting ions and connecting positive and negative electrodes in the battery, and has a direct impact on the performance of the battery. Electrolyte is mainly composed of two parts: electrolyte and additives. The current electrolyte needs to be transported and used during the production of lithium batteries, but there may be impurities and particles in the electrolyte at this time. This is because some auxiliary materials such as catalysts and solvents may be used in the production process of the electrolyte. These materials may contain impurities. If the impurities in the electrolyte are not cleaned up, it may affect the performance of the lithium battery, including reducing the battery capacity, increasing the internal resistance, and reducing the cycle life.

[0011] As a further solution of the utility model: a swivel is rotatably connected outside the fixed shaft, a handle is connected under the swivel, and the handle is clamped under the limit block.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The electrolytic material conveying device for lithium battery production is provided with a fixed plate, a shell, a chute, a limit rod, a ring and a filter. When the filter needs to be installed, the fixed plate is first placed in the shell. At this time, the fixed plate drives the ring and the filter to be clamped in the shell, and then the limit rod is inserted into the shell.
