Description

Technical Field

[0002] In the actual production process of battery cells, blue film coating of battery cells is an important process. Blue film is also called isolation film or protective film, which is an insulating material. The function of blue film is to separate each battery cell, block the impact of a single battery cell failure on other battery cells, and prevent the battery cell from being scratched.

[0003] However, after the blue film-coated battery cells are left naturally for a period of time, the blue film on the battery cells will rebound and warp due to the insufficient viscosity of the blue film. If it is replaced with a blue film with higher viscosity, the thickness of the blue film will increase and defective products produced by the blue film coating will be difficult to rework, increasing the company's manufacturing costs and reducing production efficiency. Even if the hot pressing function is added to the process of coating the battery cells with blue film, there will still be varying degrees of blue film warping. This phenomenon of blue film warping will also affect the rebound and warping of the top patch, reducing the appearance quality rate of the battery cell coating.
