碩士 === 明志科技大學 === 材料工程系碩士班 === 106 === In this study, the synthesis of sulfur doped phosphorus containing nickel oxide hexagonal nanorods on nickel foam (S-NiPO HNRDs /Ni foam) were synthesized by hydrothermal method as electrode materials with unique microstructure and enhanced electrochemistry performance in alkaline electrolyte. The S-NiPO HNRDs /Ni foam electrode owns lower electrochemical impedance compared with bare NiPO HNRDs /Ni foam substrate and exhibits exceptional capacitance performance with a high specific capacitance of 1288 F g-1 delivered at current density of 2 A g-1, while 944 F g−1 retained at 10 A g−1. In addition, the S-NiPO HNRDs // AC asymmtric supercapacit5ors (ASCs) displays a maximum energy density of 16.39 W kg-1 and maximum power density of 8000 W h kg-1.
