The Ni(OH)2 nanosheets were prepared with ethanol as the solvent and ammonia as the precipitant. The structure and morphology of Ni (OH) 2 nanosheets were characterized using X - ray diffraction (XRD) and field emission scanning electron microscopy ( FESEM ). The product obtained was characterized as β- Ni(OH) 2 nanosheets with 30 nm in thickness and 200 -400 nm in width. The supercapacitor properties were studied by cyclic vohammetry(CV) ,constant current charge/discharge and electrochemical impedance spectroscopy techniques. The results show that the obtained β - Ni (OH)2 nanosheets have excellent supercapacitor -1 properties. The specific capacitance as single electrode is up to 1 338 F · g^-1.
