高比容纳米Ni（OH）_2的制备及其电化学电容性能
Preparation and Electrochemical Capacitance Characteristics of Nano-Ni（OH）2 with High Specific Capacitance
摘要
Abstract
Ni （OH）2 nano-powders were prepared using NiC2O4·2H2O as precursor, which was synthesized by low-temperature solid-state reaction of oxalic acid and nickel acetate. Scanning electron microscopy （SEM） and X-ray diffractometry （XRD） results show that the as-prepared Ni（OH）2 powder is β- Ni（OH）2 with an average diameter of 12 nm. Electrochemical capacitance behavior of the Ni（OH）2 electrode was investigated by cyclic voltammetry, galvanostatic charge-discharge test and electrochemical impedance spectroscopy. Ni（OH）2 electrode displays a specific capacitance of 2271 F.g-1 at a current density of 1 A-g 1 and it has good steady cycling performance.关键词
