Description

Technical Field

[0001] The utility model relates to the technical field of ceramic diaphragm processing, in particular to a drying device for ceramic diaphragm processing. Background Art

[0002] As batteries become increasingly complex, the requirements for diaphragms are becoming more and more demanding and complex. As a key component of lithium-ion batteries, diaphragms play an important role in batteries: preventing contact between positive and negative electrodes; providing microporous channels for the transport of Li+ within the battery; storing electrolyte to prevent electrolyte decomposition; and preventing the diffusion of byproducts produced by the redox reactions of positive and negative electrode materials, such as lithium dendrites.

[0003] In the process of diaphragm production, the production of diaphragm is mainly completed through the steps of blending, finished slurry, coating and feeding system, unwinding, roller coating, drying, winding and the like. When drying, the diaphragm is mainly heated by a heating rod to dry the moisture. However, after the moisture evaporates, water vapor will be formed and retained in the drying box. If it is not discharged in time, it is easy to adhere to the subsequent diaphragm, thus affecting the subsequent processing of the diaphragm. Utility Model Content
