Growth of Ultrathin ZnCo(2)O(4) Nanosheets on Reduced Graphene Oxide with Enhanced Lithium Storage Properties

The growth of ultrathin ZnCo(2)O(4) nanosheets on reduced graphene oxide (denoted as rGO/ZnCo(2)O(4)) via a facile low‐temperature solution method combined with a subsequent annealing treatment is reported. With the assistance of citrate, interconnected ZnCo(2)O(4) nanosheets can assemble into hiera...

description The growth of ultrathin ZnCo(2)O(4) nanosheets on reduced graphene oxide (denoted as rGO/ZnCo(2)O(4)) via a facile low‐temperature solution method combined with a subsequent annealing treatment is reported. With the assistance of citrate, interconnected ZnCo(2)O(4) nanosheets 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/ZnCo(2)O(4) nanocomposite manifests a very stable high reversible capacity of around 960 mAh g(−1) over 100 cycles at a low current density of 90 mA g(−1) and excellent rate capability.
