More flexible battery design with ultrafast laser ablation

Press Release / September 08, 2020

The ultrashort pulse (USP) laser has been known to shine whenever highly sensitive material needs to be machined quickly yet gently. The Fraunhofer Institute for Laser Technology ILT has investigated one such application that certainly looks to have a bright future: The Aachen-based researchers developed a quick, reliable and nondestructive method of ablating lithium-ion batteries’ anode material with an ultrashort pulsed laser beam. This ablation technique exposes electrical contact points called tabs.
