Joining of Copper Foils by Capacitive Discharge Welding
In 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
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 joint heating, applicability to highly conductive materials, and the ability to join many layers of foil with a single weld.
