Syvairo

Syvairo was developed as part of research work carried out in the FoFeBat construction project at Fraunhofer FFB. During the QueEn project, the concept was developed and economically validated, as well as TCO models, and initial prototypes for transport boxes and airlocks. The underlying property rights were developed as part of Fraunhofer research. 

The classic drying room is no longer up to date

Drying rooms account for over 25% of total energy costs in battery cell factories. At the same time, requirements for dew point, process stability, and flexibility will increase in the future—especially for next-gen cell chemistries such as solid-state or lithium metal cells.

The consequences:

• High CAPEX and OPEX
• Limited scalability
• High moisture and particle input
• Competitive disadvantages of European locations compared to Asia

Instead of conditioning entire halls, microclimate control is only used where it is relevant to the process: on the material, on the equipment, at the transfer point.

The result:

• Energy requirements halved 
• Lower and more stable dew points 
• Less waste 
• Improved occupational safety 
• High flexibility for new cell formats
