Present study investigated decoration of Cu(OH)(2) with different morphologies by copper precursors, on 3D nickel foam. The Cu(OH)(2)-A (nano flower)electrode showed an excellent capacitance of 1332 Fg(-1) at current density of 2 A g(-1) compared to the Cu(OH)(2)-C (nano ribbon, 1100 F g(-1)) and Cu(OH)(2)-S (nano long leaf, 1013 F g(-1)) electrodes. Asymmetric supercapacitor (ASC) was fabricated, and showed maximum capacitance of 165 Fg(-1) at current density of 2 A g(-1) with high energy density of 66.7 Wh kg(-1) and power density of 5698 W kg(-1) with excellent stability of 80% after 10,000 cycles.
