摘要
A composite material, Ni1/3Co1/3Mn1/3(OH)(2), is synthesized by chemical precipitation method for supercapacitors' electrode material. Physical characterizations using x-ray diffraction, energy-dispersive x-ray, and scanning electron microscopy show that Ni1/3Co1/3Mn1/3(OH)(2) possesses an amorphous structure and higher specific surface area (268.5 m(2) g(-1)), which lead to a high initial specific capacitance of 1,403 F g(-1) in the potential window of 0-1.5 V. It may be a potential electrode material for future supercapacitor when its cycling stability and rate performance are addressed.
