摘要：
Mesoporous Mn3O4 nanobeads are uniformly dispersed on the surface of graphene via a facile gel-like film method proposed for the first time with the help of H2O2. Graphene can effectively improve the intrinsically poor conductivity of Mn3O4, whereas the mesopores can accommodate the huge volume swings during the repeated lithiation/delithiation processes. The Mn3O4/graphene displays extraordinary cycling stability and excellent rate performance. © 2015 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.
