| Abstract Scope |
The development of low-cost, adaptable strategies and materials to satisfy the needs of energy storage and conversion technologies, particularly for batteries and supercapacitors, are challenging. On the other hand, such materials and designated approaches are desirable in order achieve enhanced device performances in batteries and supercapacitors. In present work, we deposited three-dimensional (3-D) mesoporous nickel-based nickel oxide nanostructures thin films with improved performance for supercapacitor applications. The conformal deposition of nickel oxide nanoflakes on 3-D mesoporous nickel improves the performance of supercapacitor by increasing electrochemical surface area and ease the electron transport through interconnected nickel network. The 3-D mesoporous nickel/nickel oxide nanoflakes exhibits excellent electrochemical performance; exhibit areal capacitance of 720 mFcm−2, energy density of 4 µWhcm−2, power density of 2.5 mW cm−2 and capacitance retention of 82% after 3000 cycles. |
