摘要：

Storage shells: The assembly of negatively charged graphene oxide and positively charged oxide nanoparticles by electrostatic interactions, and subsequent chemical reduction, leads to metal oxides encapsulated in flexible and ultrathin graphene shells (see picture). These electrochemically active nanoparticles show a remarkable lithium storage capacity, with an excellent cycle performance. © 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
