Increasing round trip efficiency of hybrid Li–air battery with bifunctional catalysts
Electrochimica Acta, 2013Abstract Previously it was shown that Pt as cathode catalyst has a large overpotential during charge in rechargeable hybrid Li–air battery with sulfuric acid catholyte. This article demonstrates that a bifunctional catalyst composed of Pt and IrO 2 supported on carbon nanotubes can address this problem.

Abstract Liquid air energy storage (LAES) uses off-peak and/or renewable electricity to liquefy air and stores the electrical energy in the form of liquid air at approximately −196 °C. The liquefaction (charging) process involves multi-stage air compression with the heat of compression harvested by a thermal fluid, which is stored for use in the ...
