Abstract
Description
Technical Field
[0001] The present application relates to the field of battery technology, and in particular to a battery formation processing device and battery manufacturing equipment. Background Art
[0002] Currently, battery formation is a crucial step in the battery manufacturing process, particularly in the production of lithium-ion batteries. This process involves the initial charging of the battery cell after it has been filled with electrolyte and is typically divided into two stages: pre-formation and main formation. The primary purpose of formation is to activate the active materials in the battery and improve its overall performance.
[0003] In the prior art, battery formation failure warnings, such as those for square aluminum-shelled cells, primarily include: stopping charging when the software monitors channel temperature anomalies or abnormal charging voltage jumps; activating the smoke sensor, fire extinguisher, or water sprinkler to extinguish the fire on the battery surface if the cell fails and smoke is detected. However, when abnormal temperature or charging voltage jumps are detected, the cell may have short-circuited and ignited an internal fire. The activation of the fire extinguisher or water sprinkler can only extinguish the fire superficially. Once the fire has melted the outer shell and erupted, extinguishing the fire becomes difficult, and the failed cell will essentially burn out, affecting surrounding cells as well. This results in poor failure warning effectiveness and high post-formation failure treatment costs. Summary of the Invention
[0004] The purpose of this application is to provide a battery formation processing device and battery manufacturing equipment, which can achieve the technical effect of improving the efficiency of formation failure warning and reducing the processing cost after formation failure.
