Abstract
Nanostructured Copper oxides are promising materials for supercapacitors due to their high theoretical capacitance, low cost and environment friendly properties, especially for those prepared via template-free method. In this work, an in-situ growth of self-assembled 3D Cu2O@Cu foams nanocomposite without template has been developed and the synthesis mechanism has been discussed in detail. The electrode exhibits a high capacitance of 0.66Â FÂ cmâ2 (about 200Â FÂ gâ1) and significant stability (after 12000 times cycling, remaining 87.9% of the initial value). Extraordinary performances and relative cost of the raw material indicate its potential in commercial applications for energy storage.
