Carbon has been regarded as one of the most attractive cathode materials for non-aqueous lithium-oxygen batteries due to its excellent conductivity, high specific area, large porosity, and low cost. However, a key disadvantage of carbon electrodes lies in the fact that carbon may react with Li2O2 and electrolyte to form irreversible side products (e.g. Li2CO3) at the active surfaces, leading to a...
In this work, we synthesize inexpensive Vulcan XC-72 carbon supported Fe2O3 nanoparticles (Fe2O3/XC) as an oxygen evolution reaction (OER) catalyst for non-aqueous lithium-oxygen batteries. It is demonstrated that the battery with the Fe2O3/XC cathode exhibits a charge voltage plateau of 4.01V at a current density of 200mAg−1, which is 0.43V lower than that with the pure XC carbon cathode. The battery...
