本文采用简单的溶剂热法制备了具有介孔MnS团簇(60-150 nm)的三维石墨烯，该团簇由多个纳米粒子(10-20 nm)和孔道组成。作为锂离子电池负极材料，MnS/石墨烯纳米复合材料具有高的可逆容量、良好的循环性能和优异的倍率性能。在30次循环中，当电流密度为50 mA g(-1)时，比容量可达980 mA h g(-1)。(C)2013 Acta Materialia Inc.由Elsevier Ltd.出版。保留所有权利。
In this paper, 3-D graphene cross-linked with mesoporous MnS clusters (60-150 nm), composed of many nanoparticles (10-20 nm) and pores, was fabricated by a simple solvothermal method. As an anode material for lithium-ion batteries, the MnS/graphene nanocomposite exhibited high reversible capacity, good cycling performance and excellent rate capability. A specific capacity as high as 980 mA h g(-1) can be achieved at a current density of 50 mA g(-1) in the 30th cycle. (C) 2013 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
