Battery production

Energy storage devices such as lithium-ion batteries play a crucial role for the change in mobility and energy transition. In order to optimize the battery production, sensors are required which monitor the production line to the highest accuracy and dynamic. Micro-Epsilon offers reliable sensor technology from high precision distance sensors to infrared temperature measurement technology and 2D/3D profile sensors for multiple measurement tasks.

Process-reliable distinction of black tones in battery production

The production of lithium-ion batteries requires maximum precision. In this ultra-modern manufacturing process, carrier films are combined with an anode and a cathode to form an energy cell. The anode consists of a copper film coated with a…
