lifepo4 battery 320ah 3.2v.Adhesive technology trends and their impact on battery performance

　　"An important method to suppress electrode expansion is to add a binder. However, as the electrode piece expands and contracts during the charge and discharge process, the distance between the active materials expands, and the binder polymer will stretch." Dr. Wang Jian said that ideal The adhesive can maintain high strength under repeated stretching. Experimental studies have shown that Zeon's new adhesive product can effectively suppress the cyclic expansion of the negative electrode, improve the cycle characteristics of Si-containing negative electrode batteries, and increase energy density.

　　End users have been increasingly demanding battery performance. It has become a development trend to introduce functional coatings into battery products to improve battery performance. For example, by forming a functional coating on the surface of the separator, it can inhibit the thermal shrinkage of the separator and prevent short circuits; in the positive electrode A functional coating is introduced on the surface to reduce the increase in impedance of the battery after high-temperature storage.

　　Dr. Wang Jian introduced that based on accurate judgment of the market, Zeon has officially started the research and development of adhesives for functional coatings since 2003 and began to supply market products in 2005. With excellent performance, its products have won unanimous praise in domestic and foreign markets.

　　It is worth noting that competition in the market for adhesives for lithium batteries is becoming increasingly fierce. However, compared with its competitors, Zeon has advantages that are difficult to replace: 1. It is the world’s earliest manufacturer of binders for water-based negative electrodes. It has accumulated a large number of customers over a long period of time and has great brand influence; 2. Regardless of the In terms of R&D personnel and equipment, the R&D strength is very strong.

　　Of course, this does not mean that Rayon will "underestimate the enemy". Its sales representative, Matsu Yasuki, said: "Ziong will further strengthen information collection and always pay attention to market conditions and competitor situations in order to carry out more targeted marketing."
