Background

At present, in the lithium manganese button cell industry, when most enterprises produce cells, the adopted accessory assembly mode is wet assembly, the ring-added positive plate needs to be dried before an upper assembly line, and the dried ring-added positive plate is soaked in an electrolyte soaking box in vacuum. And the electrolyte is fully absorbed by the dried positive plate and then is transported to an automatic line for assembly. The positive electrode sheet at this time is referred to as a wet positive electrode sheet. But the positive plate can not completely bake the moisture in the positive plate to be absolutely dry in the drying process. The positive plate always contains a certain trace amount of moisture, and the moisture can be replaced into a soaking cylinder of the electrolyte in the process of electro-hydraulic vacuum soaking. And as production progresses, new positive plates are continuously added to cause the water content in the electrolyte soaking cylinder to gradually increase. This results in different moisture contents of the anode plates soaked in different batches. The consistency of the moisture content of the battery manufactured subsequently cannot be guaranteed, and the consistency of the electrical property of the battery cannot be guaranteed. In addition, the existing wet assembly process causes a large amount of electrolyte with excessive water content, and electrolyte waste is caused.
