In the production of electrodes, thin metal foils are coated with the cathode and anode material, which consists of various chemicals. Dürr will supply FIB, a Seri Industrial Group company active in the production of lithium-iron-phosphate batteries, with four lines each for cathode and anode coating. These include so-called tandem coaters, in which both sides of the foils are coated, one after the other. Other system components include, in particular, dryers, calenders for compacting the material, and cutting devices for extracting individual electrodes from the electrode foils. In addition, Dürr supplies environmental systems for recovering the solvents required for the coating process from the exhaust air and reusing them.
More and more batteries are needed worldwide, for example for electric cars, electronic devices, or to store energy for households. Dürr has been active in the battery production technology business since 2018. The order from FIB is by far the largest project in this business area to date. “This major project is of enormous strategic importance and underlines the attractiveness of our range of solutions for the large-scale production of electrodes for batteries”, says Dr. Jochen Weyrauch, CEO of Dürr AG.
Several factories for battery cells are currently being built in Europe, and this is likely to continue in the coming years. While in the past battery cells were almost exclusively sourced from Asia, the trend is now to build up own production capacities. “Europe needs its own battery industry to be able to meet its demand. For the construction of the necessary factories, many battery manufacturers want European technology suppliers as an alternative to Asian suppliers. This is exactly what Dürr stands for: We know the needs of European customers, we have recognized technologies at our disposal, and we know how to build and commission production systems safely and on schedule,” says Dr. Jochen Weyrauch.
Installation of the systems for FIB is scheduled to begin in the fall of 2025. Start of production is planned during 2026.
