Problems solved by technology

This lithium battery drying method is inefficient and relies on labor, especially when the lithium battery is re-exposed to the atmosphere during transportation. Moisture and impurities in the air will enter again and affect the quality of the battery. The liquid injection process in the liquid production line also needs to be completed manually in the glove box

Description

technical field [0001] The invention designs lithium battery production technology, specifically a lithium battery dry injection tank production line. Background technique [0002] The carbon material negative electrodes used in lithium batteries all use the porous adsorption characteristics of carbon materials and the super large specific surface. The water, gas and impurities rich in the gaps will seriously affect the performance indicators of the battery. Before electrolyte injection, a final step is required. dry. The existing drying process is to manually put the cell to be liquid-filled into the drying box through a trolley, dry it for about 48 hours, and then manually push it out and send it to the next station of lithium battery processing for liquid injection. This lithium battery drying method is inefficient and relies on labor, especially when the lithium battery is re-exposed to the atmosphere during transportation. Moisture and impurities in the air will enter ...
