Abstract
Description
Technical Field
[0001] This utility model relates to the field of lithium battery cell drying technology, specifically to a lithium battery cell production drying device. Background Technology
[0002] A drying device is a combination of mechanical equipment that uses certain technical means to dry the surface of an object of moisture or other liquids. The main principle of a drying device is to evaporate the excess moisture of the item being dried. This moisture can evaporate into water vapor after absorbing heat. Subsequently, the air generated in the drying device blows the water out of the device, thereby carrying away the moisture from the damp item and achieving the purpose of drying. There are various types of drying devices, the main types being box-type, tunnel-type, and rotary dryers. Drying devices are used to dry liquid coatings to produce powdered or solid products. Lithium-ion batteries are rechargeable batteries widely used in various portable electronic devices, electric vehicles, drones, power tools, and other fields. They are known for their high energy density, lightweight, rechargeability, and low self-discharge rate, making them a key part of modern battery technology. Among them, the battery cell is an important part of the lithium-ion battery, which is convenient for storage and transportation. During the processing of the battery cell, it is necessary to dry the coating sprayed on the cell or the residual moisture after cleaning.
[0003] Existing lithium battery cells are dried using hot air during the drying process, but only one side is dried, and the other side cannot directly contact the hot air. This results in low drying efficiency for lithium battery cells. In addition, the drying device can only clamp and dry lithium battery cells of one size, which is not convenient to use.
