技术领域technical field

背景技术Background technique
在电池生产过程中，锂离子电池极片的补锂工艺是提高锂离子电池容量的关键技术。补锂工艺的关键在于压延与覆膜，压延工艺就是把具有一定厚度的锂带压延成锂膜，并附着在牵引膜上的一种工艺。目前采用压延装置对锂带进行压延时，由于来料锂带本身的硬度和厚度不均，会导致压延得到的锂膜的厚度不一致。In the battery production process, the lithium supplementation process of lithium-ion battery pole pieces is a key technology to improve the capacity of lithium-ion batteries. The key to the lithium supplementation process lies in calendering and film coating. The calendering process is a process in which a lithium strip with a certain thickness is rolled into a lithium film and attached to the traction film. At present, when the calendering device is used to calender the lithium ribbon, due to the uneven hardness and thickness of the incoming lithium ribbon itself, the thickness of the calendered lithium film will be inconsistent.
目前会采用热风和冷风交替对进入压延装置的锂带进行加热和降温，但是这种方式不能对温度进行准确控制，若热风的温度太高，会导致锂带太软，压延得到的锂膜的表面质量和厚度变化较大；若冷风的温度太低，会导致锂带的硬度太高、易脆。At present, hot air and cold air are alternately used to heat and cool the lithium ribbon entering the calendering device, but this method cannot accurately control the temperature. If the temperature of the hot air is too high, the lithium ribbon will be too soft, and the lithium film obtained by calendering will be too soft. The surface quality and thickness vary greatly; if the temperature of the cold air is too low, the hardness of the lithium ribbon will be too high and brittle.
