Batteries

As the electric vehicle industry continues to grow, the pressure on automotive suppliers and OEMs to deliver leak-free battery enclosures — an expensive and critical component — grows as well. Not reflected in the importance of these enclosures is the effectiveness of traditional leak detections methods. Current techniques may be expensive, difficult to implement, or...

Ultrasonic 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...

Laser welding techniques are exceptionally well suited for the electrification industry due to the technology’s high speed, low-heat input, precision, and versatility. However, changing the variables of a laser welding application – power, wavelength, travel speed, material, and more – can greatly impact the success of a weld. Laser specialists Dean Langenkamp and Jacob Hay...
