Zinc oxide/tin oxide nanoflower-based asymmetric supercapacitors for enhanced energy storage devices.

Research on energy storage devices has focused on improving asymmetric supercapacitors (ASCs) by utilizing two different electrode materials. In this work, we have successfully prepared a unique material, ZnO/SnO nanoflower, the hydrothermal method. Graphene oxide (GO) was synthesized by applying the modified Hummers' technique.
