The nanostructure exhibited a dandelion-like morphology decorated with NiO nanoparticles. Further XPS analysis clearly shows the presence of Cu and Ni with valency states. Electrochemical tests conducted in a 5 M NaOH electrolyte revealed that the introduction of 1% NiO significantly improved the charge–discharge performance, exhibiting low internal resistance and well-defined symmetric cyclic behaviour, which is crucial for redox reactions.

The construction of a full-cell symmetric capacitor utilising 1% NiO-decorated CuO in a CR 2032-coin cell yielded 89.7% capacitance retention over 2000 cycles at 0.2 A g−1 and a high Coulombic efficiency of 92.5%.
