Abstract
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 m² 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.
