High-Speed Adhesive Dispensing for High-Voltage Batteries
The high viscosity and high proportion of abrasive fillers in the pastes, adhesives, and sealants used to assemble high-voltage batteries requires specialized dispensing and filling technologies.
Thermal influences can significantly affect the service life, capacity, and—above all—operational safety of high-voltage (HV) batteries. In order to prevent damage caused by excessive temperatures, large quantities of thermally conductive pastes, adhesives, and sealants are used. Since the high viscosity and the high proportion of abrasive fillers in these materials usually only allow comparatively low dispensing speeds, it is all the more important to have a high-performance system technology that is precisely matched to the application.
Electric mobility is picking up speed: Vehicles with alternative drive systems are regarded as a key component in the fight against noise pollution and constantly rising emissions in densely populated areas. With a view to current environmental and climate protection targets, various European countries are already planning to abandon the combustion engine. China, which is currently the world’s largest market for electric vehicles, reported over 1 million electric cars sold last year. According to management consultancy McKinsey, the local market grew by 85% in 2018.
