Carbon coated MnO@Mn3N2 core–shell composites for high performance lithium ion battery anodes†
Abstract
Carbon coated MnO@Mn3N2 core–shell composites (MnO@Mn3N2/C) were synthesized in a simple approach by calcining MnO2 nanowires with urea at 800 °C under an ammonia atmosphere. Urea derived carbon nanosheets were partially coated on pure phase MnO@Mn3N2 core–shell composites. Electrochemical measurements reveal that the MnO@Mn3N2/C displayed high discharge capacities, an excellent high-rate capability and an enhanced cycling performance.
