摘要：

Charged up: Three-dimensional architectures constructed from graphene/MoS2 nanoflake arrays have been successfully fabricated by a one-step hydrothermal method. MoS2 nanoflakes with thicknesses less than 13 nm grow vertically on both sides of graphene sheets (see figure), which allows the architectures to be more stable during charging and discharging. Even at a high current density of 8000 mA g-1, their discharge capacity is still up to 516 mA h g-1. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
