Dürr and Grob: Production technology for battery cells
Dürr and Grob are continuing their strategic cooperation in the field of production technology for battery cells. Both partners are already realizing their first projects, such as the installation of systems for the classic wet coating of electrodes.
In September 2022, Dürr AG, Grob-Werke GmbH & Co. KG and Manz AG entered into a strategic partnership for the joint acquisition and processing of projects to equip complete battery factories. Even after the withdrawal of Manz, the aim of the partnership remains to jointly establish themselves as a system provider of battery production systems in Europe and North America. This offers customers a high-performance alternative to the equipment suppliers that have mostly come from Asia to date. Last year, Dürr and Grob expanded their machine and system portfolios for the production of battery cells and made them more efficient. Process steps previously covered by Manz can now be taken over by the two remaining partners.
Strategic cooperation for battery cell production
The strategic cooperation focuses on the automotive sector and the market for stationary battery storage systems, where demand is growing significantly. Stationary storage systems absorb surplus energy from solar and wind power so that fluctuations in the power supply can be balanced out. They also serve as home storage solutions for solar power from private systems. Although electromobility is currently progressing more slowly than expected, it is causing demand for battery production technology to rise sharply. Several battery and car manufacturers in Europe are therefore investing in battery factories. They are building up their own production capacities instead of buying battery cells almost exclusively from Asia, as was previously the case. The cooperation between Dürr and Grob aims to minimize energy consumption in cell production and increase the quality of the battery cells produced. "We achieve this on the one hand through the high availability of our automated machines and systems and on the other hand through an end-to-end digitalization concept that allows our customers to monitor all production steps," explains Dr. Jochen Weyrauch, CEO of Dürr AG.
Major Dürr order from battery manufacturer
In December, Dürr received a major order from Italian battery manufacturer FIB and will install a turnkey system for electrode coating at the plant in Teverola near Naples. The system is designed for the production of lithium-ion battery cells with a total output of 8 gigawatt hours per year. The cooperation partners are already implementing their first projects together. For example, Dürr and Grob are supplying a European cell manufacturer with machines for the production of high-performance battery cells. Dürr is installing systems for the classic wet coating of electrodes, which corresponds to the current state of the art, and is planning a pilot system for efficient and sustainable dry coating. Grob supplies the complete cell assembly based on innovative lamination technology, which enables a significant increase in production speed and therefore low manufacturing costs.
