Read MoreElectric 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 […]
Read MoreIn battery manufacturing, foils are attached via ultrasonic metal welding, an effective method with some significant drawbacks. These include debris generation, fatigue and cracking, and difficulty with in-process monitoring. EWI has recently been working with an alternative joining technique for battery foils, capacitive discharge (CD) welding. Its advantages include rapid thermal cycling results, highly localized […]
