Carbon coated MnO@Mn3N2 core-shell composites for high performance lithium ion battery anodes.
Carbon coated MnO@Mn(3)N(2) core-shell composites (MnO@Mn(3)N(2)/C) were synthesized in a simple approach by calcining MnO(2) nanowires with urea at 800 °C under an ammonia atmosphere. Urea derived carbon nanosheets were partially coated on pure phase MnO@Mn(3)N(2) core-shell composites. Electrochemical measurements reveal that the MnO@Mn(3)N(2)/C displayed high discharge capacities, an excellent high-rate capability and an enhanced cycling performance.
