The lithium battery cover is an important component of the lithium battery. It is mainly responsible for sealing the positive and negative electrodes and electrolyte of the battery to prevent electrolyte leakage and safety accidents. When processing the lithium battery cover, the lithium battery cover needs to be dried at low temperature to avoid moisture affecting subsequent processing.

[0003] A Chinese patent discloses a low-temperature drying device for processing lithium battery cover plates (authorization announcement number CN217110241U). When drying the lithium battery cover plates, the cold air machines on both sides will dry the two sides of the lithium battery cover plates at low temperatures respectively, without the need to actively turn the lithium battery cover plates over.
