The batteries used in EVs need to have a good quality as the battery should preferably last as long as the vehicle is in use. Easy to recharge as fast as possible and needs to be a reliable power supply during trips/commutes. To ensure this there are several quality control parameters during the battery production. One of the key parameters for quality control is the thickness (and width) of film and strip materials, wet layers and electrode coatings. Yokogawa has been involved in measuring the thickness of battery films and electrodes in the past decades. By utilizing a Beta-ray source, our WEBFREX3ES measures the film thickness reliably and helps to identify a coating that’s too thin or missing.
