Ruthenium nanocrystals as cathode catalysts for lithium-oxygen batteries with a superior performance

Abstract

The key factor to improve the electrochemical performance of Li-O₂ batteries is to find effective cathode catalysts to promote the oxygen reduction and oxygen evolution reactions. Herein, we report the synthesis of an effective cathode catalyst of ruthenium nanocrystals supported on carbon black substrate by a surfactant assisting method. The as-prepared… (More)
