Read MoreUltrasonic metal welding is one of the most effective ways to join lithium-ion batteries. However, the need to completely replace the sonotrode due to tool wear is a limiting factor for manufacturers who are performing tens of thousands of welds per day. EWI has designed and validated a sonotrode with a replaceable tip made of […]
Read MoreHarnessing the Power of FEA Part 1: Introducing Finite Element Analysis By Amin Moghaddas Finite Element Analysis (FEA) is a powerful numerical method used to solve complex engineering problems, particularly those involving intricate geometries, loadings, and material properties where analytical solutions may not be feasible. By breaking down complex systems into smaller elements, FEA allows […]
Read MoreUltrasonic wire bonding (UWB), today’s preferred method for joining wires to battery packs in electric vehicles, requires very high surface cleanliness to assure successful bonds. Decontaminating battery terminals, however, can be a very difficult and time-consuming task. EWI has recently completed a study using laser cleaning technology on batteries prior to UWB of aluminum wire […]
