UV coating on the surface of the battery shell: Start a new journey of battery protection and performance improvement

With the continuous progress of science and technology, batteries are more and more widely used in various fields, and the performance and safety requirements of batteries are also increasing. As an important part of the battery, the battery shell not only plays a role in protecting the internal cell, but also affects the appearance and service life of the battery. In this context, the technology of UV coating on the surface of the battery shell came into being and has been widely used.

UV coating is a coating that can quickly cure into a film under ultraviolet irradiation. Compared with traditional coatings, it has the remarkable characteristics of fast curing speed and high production efficiency. Traditional coatings may take hours or even days to completely dry, while UV coatings can complete the curing process in just a few seconds under ultraviolet irradiation, greatly shortening the production cycle and improving production efficiency. This means higher production capacity and lower costs for large-scale battery manufacturers.

In terms of protection performance, UV coatings also perform well. It can form a hard, wear-resistant, corrosion-resistant protective film on the surface of the battery shell, effectively resisting external physical impact, chemical corrosion and ultraviolet erosion. The experimental data show that the wear resistance of the battery shell treated with UV coating is more than 30% higher than that of the untreated battery shell, and the corrosion resistance is also significantly improved. This enables the battery to maintain good performance in harsh environments and extends the service life of the battery.

UV coatings also have good insulation properties. During the working process of the battery, the battery shell needs to have a certain insulation ability to prevent current leakage and short circuit accidents. The insulation performance of UV coating can meet this requirement, providing a reliable guarantee for the safe operation of the battery. At the same time, the transparency of the UV coating is high, which will not affect the appearance of the battery shell, but also make the surface more smooth and bright, and improve the overall beauty of the battery.

In terms of spraying process, the operation of spraying UV coating on the surface of the battery shell is relatively simple. First of all, it is necessary to clean the surface of the battery shell to remove impurities such as oil and dust on the surface to ensure that the coating can be evenly attached. Then, the UV coating is evenly sprayed on the surface of the battery shell, and it is quickly cured by ultraviolet irradiation. In the spraying process, it is necessary to control the thickness of the coating and the uniformity of the spraying to ensure the quality of the coating.

However, there are some issues that need to be noted when using UV coatings. For example, the power and irradiation time of the UV irradiation equipment need to be reasonably adjusted according to the characteristics of the coating to ensure that the coating can be fully cured. At the same time, the storage and use of UV coatings need to pay attention to safety issues such as fire prevention and explosion prevention.

In short, UV coating on the surface of the battery shell is an advanced protection technology, which brings new opportunities for the development of the battery. It is believed that in the future, with the continuous progress of technology, UV coatings will play a more important role in the field of battery manufacturing.
