Optimizing Ultrasonic Knurl Patterns with FEA
Electric vehicles and consumer electronics depend on high-capacity, highly efficient batteries, and the demand continues to rise. Critical to producing these batteries is the successful welding of foil-to-tab joints which are often made of dissimilar materials with dissimilar thicknesses. This process is complicated, and the failure of a single joint will compromise an entire battery […]
