ECC-Air

Electrochemical Test Cell

The ECC-AIR is another member of the modular ECC series dedicated to the electrochemical characterization of gas diffusion electrodes in aprotic electrolytes, e.g. for lithium-air batteries. Basically, the upper diffusion type electrode is contacted by, and “breathes” through the perforated stainless steel current collector (plate) on top. The gas volume inside the cell above the perforated plate is accessible via a port in the cell lid. The design includes a reference electrode.

Features

  • High precision 18 mm diameter sandwich geometry with better than 0.1mm concentricity
  • Adjustable, reproducible and homogeneous mechanical pressure on electrodes
  • Reliable low leakage sealing with PE washers, He leakage rate <10E-8 std cm3/s
  • Easy and reliable electrolyte filling either upon assembly or afterwards via syringe
  • Fast assembly and dismantling, and easy cleaning of cell components
  • Electrodes are easily accessible for post-mortem analysis
  • Reusable cell components except for PE sealing
  • Small and defined electrolyte volume down to 0.1 cm3 due to minimized dead volume
  • Materials in media contact are  stainless steel and PEEK
