Presentation title：
The application of new adhesives in new energy vehicle industry

Presentation Description：
Carbon reduction in the transportation field is an important part of carbon peaking and carbon neutrality global goals. The development of new energy vehicle is the key to promote innovation of energy structure and achieve low-carbon goal in this field. Power battery is the heart of new energy vehicle, while different kinds of adhesives are necessary tissues in this heart. Electrode binder, separator binder, and adhesive for battery pack are the three kinds of adhesives used in power battery. The adhesives help to increase the energy density of battery which is beneficial to long-distance driving, and solve safety problems. At the same time, the components of adhesives upgrade toward environmental friendly. Based on the above principles, we develop water-based polyacrylic products used in the silicon anode, which interact with silicon anode materials strongly and perform high strength to cope with the high expansion of silicon anode. And another polyacrylic emulsion with good adhesion used on cell separator as an adhesive functional layer is developed to keep the cell work efficiently. In addition, the low density silicone sealant with low density flame retardant composed of silsesquioxane, and thermal conductive structural adhesive composed of silicone modified polyurethane with fatigue resistance and flame retardant functions are both developed. These adhesives are applied to battery pack to decrease the pack weight and increase fire safety effectively. A vision of the application of new adhesives is that the penetration rate of new energy vehicle could be increased as a result and carbon reduction could be promoted.
