In situ Formed Au Nanolayer as a Bifunctional Catalyst for Li-air Batteries†

doi:10.7503/cjcu20150882

Abstract

Abstract:

Au nanolayers(ANL) were in situ formed on the Ni foam(SP) via the galvanic exchange method. The as-prepared ANL/SP was applied as the current collector of air cathode for the Li-air battery which operated in pure O₂, ambient air and simulated air. The electrochemical performances of ANL/SP electrode for Li-O₂ battery were investigated. The results showed that the in situ incorporation of ANL significantly improves the energy output and the cycling performance of the aprotic Li-O₂ battery in ambient or simulated air, and effectively facilitates the oxygen reduction/evolution reactions(ORR/OER) kinetics of the O₂ electrode in simulated air.
