Preparation of New Multi-Component Nanometer Manganese Dioxide/Carbon for Air Electrode

Abstract:

Lithium air batteries have aroused a considerable concern all over the world owing to their outstanding performances. Especially, catalysts of the air electrode, as one of the most core components of lithium air batteries, have been most extensively studied in recent years. In this paper the nanometer manganese dioxide catalysts and their compounds with Super P, TNRGO and OMC were prepared successfully via hydrothermal synthetic method. Characterized by XRD, SEM and BET, most of them have regular shape, perfect dispersion and high specific surface area, especially S_BET of MnO₂/TNRGO/OMC of the three-component catalysts was up to 126.70m²/g. The air electrodes with nanoMn0₂/carbons catalysts have lower resistance, and better reversibility.
