STÉPHANE MELANÇONLaser technology has become an increasingly vital tool in the production of batteries for electric vehicles (EVs). High-power laser tools are now commonly used to process materials at several steps during the production of EV batteries. Lasers cut anode and cathode materials. They clean electrolytes, dust, and other contaminants from parts before welding. And as coherent light sources, they are used to weld foils, tabs, cell connectors, cell cans, busbars, and other battery pack components. Lasers also clean and texture surfaces to prepare them for bonding, and they mark components for...Read full articleRelated content from Photonics MediaARTICLESEvaluating Off-the-Shelf Optical ComponentsOff-the-shelf optical components offer a number of advantages for optical system design, including shorter delivery times, lower costs, and quicker replacement.
