More flexible battery design with ultrafast laser ablation

Fast, gentle and reliable: The Fraunhofer ILT has come up with a process tailor-made to ablate anode material from very thin copper foils at up to 1760 mm³/min. It uses a powerful USP laser to expose surfaces for electrical contacts. (Fraunhofer ILT, Aachen, Germany.) Image Zoom
