The Dry Room where the cell prototyping line is installed, provides an ultra-dry environment required to handle some novel materials and technologies allowing the processing and assemblying of energy storage devices close to the industrial processes. Dry room provides a safe environment that allows to work with alkaline metals such as lithium or sodium metal and any other moisture sensitive material which are called to lead the coming future of the energy storage. It gives the chance to face and understand the processability problems and therefore provides information for further tuning of the materials improving their performance, developing the technology and reducing technological risks providing competitiveness of the companies.
The platform has the capability to scale up materials from gr to kg per batch, slurry formulation up to 5 liters, double side electrode coating in a roll to roll system in continuous or pattern coatings up to 225mm wide, solid electrolyte membrane extrusion and monolayer or multilayer pouch cell assembly both for liquid and solid electrolyte.
The main characteristics of the platform are:
Controlled Dew point: - 60 C degrees
Controlled Temperature: 21 °C degrees ± 1 °C
7 class ISO clean room
Overpressure: 30 Pa
Every parameter is monitored with a SCADA system, from the air generation system, air flow, recirculation, room parameters, ensuring a safe and comfortable environment to the researches.
CIC Energigune usually works with a pouch cell with 41x60 mm geometry although tools could be changed in order to manufacture bigger cells under request. Monolayer pouch cell can be prototyped for preliminary data and for bigger capacities, multiple layer pouch cell with a maximum thickness of 5mm.
The open platform concept, allows the cooperation with universities, other centers or private companies while retaining the confidentiality.
