Description

CIDETEC’s dry-room infrastructure consists of five interconnected areas, covering a total of 480 m² and operating under ultra-low-humidity conditions, with a dew point of −50°C.

These rooms enable the safe and stable processing of moisture-sensitive materials, such as liquid and solid electrolytes, and are essential for assembling lithium-ion, sodium-ion, solid-state, and emerging-technology battery cells. They are used for research, development, and pilot-scale production in a controlled cleanroom environment.

Equipment

  • Five interconnected dry rooms with environmental control.
  • Dew point of ≤ −50°C in all areas.
  • Continuous air recirculation and drying system.
  • Dedicated areas for mixing, coating, cell assembly, and sealing.
  • Equipment for the safe handling of solvents.
  • Integration with the pilot plant and testing laboratories.
Services
  • Processing of moisture-sensitive materials.
  • Battery cell assembly under industrial conditions.
  • Safe handling of electrolytes, salts, and electrodes.
  • Support for projects involving sodium-ion (Na-ion), lithium-ion (Li-ion), solid-state batteries (SSB), lithium-sulfur (Li-S), and other technologies.
  • Reproducible environmental conditions for R&D and validation.
  • Services for industrial clients and international consortia.
