While ultrasonic and laser welding are both effective methods for battery foil welding, neither can be monitored in process. So when a battery batch is defective, the problem is not identified until after material, time, and money as been spent. EWI recently tested a resistance spot welding technique that uses a capacitive discharge power supply […]
Read MoreThe integrity and reliability of joints in lithium-ion battery packs is critically important to manufacturers in industries ranging from automotive to consumer electronics to aerospace. If battery packs fail, it can result in more than just a faulty product — it can actually be a threat to public safety. Many welding techniques are used to […]
Read MoreEWI has developed a novel ultrasonic metal welding (UMW) knurl design which significantly improves the quality of foil-to-tab joints in lithium-ion battery cells. The new design allows multiple-layers to be joined in a single operation without pre-consolidation of the foils and without the use of buffer material or thicker sandwich foils.
