| Abstract Scope |
Electric vehicle battery packs consist of a large number of battery cells which must be assembled together with robust mechanical and electrical joints. One of the challenges in battery manufacturing is to join highly conductive and dissimilar multilayer materials such as Al and Cu sheets to foils with 100% reliability. Micro friction stir spot welding (MFSSW) is a spot-like joining process utilizing a non-consumable tool to generate frictional heat and join multilayer materials under the solid-state condition. This present work investigates the capability of MFSSW thirty aluminum foils sandwiched between aluminum and copper sheets. The joint strength and electrical conductivity in relation to MFSSW force/torque and temperature are characterized and presented. |
