Changes in the field of cell insulation: the dilemma of PET blue film and the rise of UV spraying

In the stage of cell insulation, the PET blue film that once occupied a place is now facing the fate of being eliminated. PET blue film in the past application, although it can provide a certain degree of insulation protection, but its own many limitations are gradually exposed. For example, its high temperature resistance is limited, and in the case of high heat generated by the battery cell for a long time, there may be a risk of performance degradation or even failure, which poses a potential threat to the safety of the battery cell. Moreover, the flexibility and fit degree of PET blue film is also difficult to meet the increasingly complex cell structure design needs, prone to wrinkles, gaps and other problems, affecting the integrity of the insulation effect.

In sharp contrast, cell insulation UV spraying technology is emerging, showing a number of significant advantages. First of all, UV spraying can form a layer of uniform, dense and strong adhesion insulation coating, perfectly fit the various shapes and surfaces of the cell, effectively avoid the generation of gaps and bubbles, and greatly improve the reliability of insulation. Secondly, UV coating has excellent high temperature resistance and aging resistance, which can play a long-term and stable insulating role in the complex working environment of the battery cell to ensure the safe operation of the battery cell. In addition, the UV spraying process is relatively environmentally friendly, in line with the current pursuit of green manufacturing, reducing the environmental pollution problems that may be caused by traditional insulation materials.

With the influx of 19 + UV coatings & engineering companies, this new coating track has become increasingly hot. These companies have brought advanced technology and rich experience to promote the rapid development of UV spray technology in the field of cell insulation. They continue to optimize the coating formulation and improve the accuracy and efficiency of the spraying process, so that UV spraying can better meet the individual needs of different cell manufacturers. In this new track, the competition and cooperation between the companies coexist, and jointly explore the best solution of cell insulation, which has injected a strong impetus for the upgrading of the entire industry. It can be predicted that in the near future, UV spraying will gradually replace PET blue film and become the mainstream technology of cell insulation, leading the cell manufacturing industry to a new era of safer, more efficient and environmentally friendly.
