// Large Li-ion cells production (FPL)

"Our interdisciplinary, highly-qualified team guarantees not only the reliable operation of the systems but also supports our industrial partners in cost monitoring and new quality assurance methods."

 

The research prodution line (FPL) for Li-ion cells includes all systems used in a commercial production. As a result, innovative cells can be manufactured in a reproducible manner and in high quality in sample lines. The systems, from paste production through coating and assembly to formation, are deliberately not linked to one another. This enables the flexible and progressive integration and testing of new manufacturing processes in pilot production.

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

Facilities

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
