title: Growth of Ultrathin ZnCo2O4Nanosheets on Reduced Graphene Oxide with Enhanced Lithium Storage Properties.
abstract: The growth of ultrathin ZnCo2O4nanosheets on reduced graphene oxide (denoted as rGO/ZnCo2O4) via a facile low-temperature solution method combined with a subsequent annealing treatment is reported. With the assistance of citrate, interconnected ZnCo2O4nanosheets can assemble into hierarchically porous overlays on both sides of rGO sheets. Such a hybrid nanostructure would effectively faciliate the charge transport and accommodate volume variation upon prolonged charge/discharge cycling for reversible lithium storage. As a result, the rGO/ZnCo2O4nanocomposite manifests a very stable high reversible capacity of around 960 mAh g-1over 100 cycles at a low current density of 90 mA g-1and excellent rate capability.
