Metal Air Systems

Three metal air systems are of interest to us:

  • Lithium Air
  • Zinc Air
  • Aluminum Air

The GDE The Interface diagram

Our researchers are focused on overcoming the “bottle-neck” issues of Lithium Air batteries:

  • Development of a functional 3-dimensional, 3-phase gas-diffusion-electrode in non-aqueous electrolyte;
  • Avoidance of the GDE passivation by the deposition of oxygen reduction products;
  • Prevention of the chemical reaction between superoxide ions with organic solvents and increase of oxygen solubility and diffusion rate in non-aqueous electrolytes.

We also investigate non-noble metal catalysts, the carbon material for the oxygen reduction, and
engineering designs for the GDE, cells, and battery package.
