摘要：
Graphene-wrapped organic nanoflowers are synthesized from ultrasonic treatment of a simple microsized disodium salt (Na2C12H6O4) and graphene, which demonstrates a greatly enhanced electrochemical capacity, rate capability and cycling stability as organic Na+ storage anode. This work suggests an effective architecture to make organic materials electrochemically energetic and stable for energy storage applications. © 2015 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.
