When it comes to joining dissimilar materials in lithium-ion batteries, ultrasonic metal welding is fast and efficient. However, due to tool wear, the sonotrodes used in battery joining have to be completely replaced frequently.
EWI has developed a new design approach that uses finite element analysis (FEA) to evaluate ultrasonic welding tools with replaceable knurl pads. As a result, new sonotrodes can be custom-designed for specific applications, quickly validated, and deployed.
You are invited to learn more about this approach in Sonotrode Design for Ultrasonic Metal Welding of Lithium-ion Batteries using Finite Element Analysis, written by EWI Project Engineer Amin Moghaddas. To view this paper, at no charge, simply complete the form on this page.
