// Large Li-ion cells production (FPL)

Our research production line (FPL) for industry-scale production mirrors commercial production equipment. This enables the reproducible production of innovative lithium-ion cells in sample series of the highest quality. From paste production to coating and formation, the equipment is not linked. This allows flexible integration and pilot production testing of new advanced manufacturing processes.

Our qualified and experienced team ensures the reliable operation of the equipment and provides comprehensive support to industry partners in cost analysis and the implementation of new quality assurance methods.

Range of services

  • Demonstration of advanced active materials and compositions in standard cells
  • Evaluation of new materials and components for production in an industry-relevant environment
  • Testing and optimisation of new production methods and system components in modular and process-secure test environment
  • Further development of the process parameters crucial for quality and yield, and quality assurance methods in the close-to-production environment


Slurry preparation

  • Automatic weighing and feeding of the materials
  • Mixer with temperature control for producing paste in batches of up to 60 l

Electrode production

  • Two-storey electrode coating system for double-sided coating with 500 mm coating width, 30 m/min belt speed and various application systems
  • Precision calendar with 600 mm width drums
  • Slitter winder (30 m/min) with exchangeable cutting units, each with 4 blades and brush system to clean the cut electrode belts
  • Laser cutter

Cell assembly / cell formation

  • Fully automated assembly and filling systems for PHEV-2 cells (up to 80Ah).
  • 300 m² dry room (dew point -60 °C) for testing new assembly technologies
  • Fully automated formation with 240 temperature-controlled stations for cyclisation and 2,016 storage stations
