Innovative Equipment Solutions for the Next Generation of Battery Cells
The performance of modern battery systems begins at the cell level. Our equipment solutions for battery cell assembly enable the cost-effective and scalable production of cylindrical cells, prismatic cells, and pouch cells—from the development of initial prototypes to fully automated mass production.
With in-depth process expertise, our own application laboratory, and a comprehensive automation strategy, we support manufacturers worldwide in the production of high-performance battery cells.
The battery cell is at the heart of every battery system. Quality, energy density, service life, and safety are largely determined by the precision of the manufacturing and assembly processes.
Modern applications in electric mobility, robotics, drone technology, and stationary energy storage place the highest demands on production quality, process stability, and scalability.
Our process equipment enables the industrial production of battery cells with reproducible processes, high equipment availability, and maximum product quality.
Production Solutions for Prismatic Cells, Pouch Cells, and Cylindrical Cells
GROB offers solutions for the mechanical processes involved in cell manufacturing—from cell cutting and stacking through cell assembly to formation and aging.
Our equipment solutions enable the flexible assembly of various lithium-ion battery cells and cell formats. From the development of new cell concepts to industrial mass production, we implement scalable production systems to meet the requirements of modern energy storage technologies.
Prismatic cell formats offer high volumetric energy density and are used primarily in battery electric vehicles and industrial energy storage systems.
The precise assembly of the cell components is crucial for the cell’s subsequent performance.
Pouch cells allow for a particularly flexible design while remaining lightweight.
Due to their high energy density, they are increasingly being used in vehicles, robots, drones, and other mobile applications.
Cylindrical cells stand out for their robust construction and high process stability.
Thanks to their performance and scalability, they are used in battery electric vehicles, energy storage systems, robotics applications, and drone technology.
Cell Stack Production Using Z-Folding & Lamination
The assembly of the battery cell stack is one of the key steps in battery cell manufacturing.
Z-Folding
Z-folding is currently one of the most established methods for battery cell stack production and is used in numerous gigafactories worldwide. The precise folding of separators and electrodes results in high-quality battery cell stacks with reproducible geometry and high process reliability.
Advantages of Z-Folding
- Proven technology for mass production
- High process stability
- Precise positioning of the electrodes
- Scalability for large production volumes
Lamination
Lamination enables the continuous processing of electrodes and separators. This results in battery cell stacks based on laminated single cells, which open up new possibilities in terms of efficiency and automation.
Advantages of Lamination
- Continuous production process
- High degree of automation
- Fewer process steps
- Future-oriented manufacturing technology
From Battery Cell Development to Scalable Mass Production
The industrialization of modern battery cells requires far more than individual machines or isolated manufacturing steps. A holistic approach that integrates product development, process validation, and production systems is crucial.
We support our customers throughout the entire development and production process—from the initial idea to fully automated series production. Even in the early stages of a project, we provide support through concurrent engineering, the development of new manufacturing concepts, and the verification of individual process steps. Through prototyping and pilot production, we lay the foundation for a smooth production ramp-up and cost-effective industrialization.
Our modular plant concepts enable flexible scaling of production capacities—from laboratory and pilot plants to production systems for gigafactories. Thanks to high format flexibility and the ability to integrate future cell generations, investments are secured for the long term.
By combining engineering expertise, automation technology, and a high degree of vertical integration, we create production solutions that meet the requirements of both current and future battery cell manufacturing.
In-house application laboratory for development and validation
In our application laboratory, manufacturing processes are developed, tested, and optimized under conditions that closely mimic real-world scenarios. This allows us to minimize risks early on and validate production parameters even before they are implemented in mass production.
